However, in + PyCrypto 2.5 and earlier, g is more simply the generator of a random + sub-group of Z^*_p. + + The result is that the signature space (when the key is used for + signing) or the public key space (when the key is used for encryption) + may be greatly reduced from its expected size of log(p) bits, possibly + down to 1 bit (the worst case if the order of g is 2). + + While it has not been confirmed, it has also been suggested that an + attacker might be able to use this fact to determine the private key. + + Anyone using ElGamal keys should generate new keys as soon as practical. + + Any additional information about this bug will be tracked at + https://bugs.launchpad.net/pycrypto/+bug/985164 + + * Huge documentation cleanup (thanks: Legrandin). + + * Added more tests, including test vectors from NIST 800-38A + (thanks: Legrandin) + + * Remove broken MODE_PGP, which never actually worked properly. + A new mode, MODE_OPENPGP, has been added for people wishing to write + OpenPGP implementations.

We now have + a decent, easy-to-use non-textbook RSA implementation. Yay! + + * Added PKCS#1 signature schemes (v1.5 and PSS). v1.5 required some + extensive changes to Hash modules to contain the algorithm specific + ASN.1 OID. To that end, we now always have a (thin) Python module to + hide the one in pure C. + + * Added 2 standard Key Derivation Functions (PBKDF1 and PBKDF2). + + * Added export/import of RSA keys in OpenSSH and PKCS#8 formats. + + * Added password-protected export/import of RSA keys (one old method + for PKCS#8 PEM only). + + * Added ability to generate RSA key pairs with configurable public + exponent e. + + * Added ability to construct an RSA key pair even if only the private + exponent d is known, and not p and q. + + * Added SHA-2 C source code (fully from Lorenz Quack). + + * Unit tests for all the above. + + * Updates to documentation (both inline and in Doc/pycrypt.rst) + + * All of the above changes were put together by Legrandin (Thanks!) + + * Minor bug fixes (setup.py and tests). + +2.4.1 +===== + * Fix "error: Setup script exited with error: src/config.h: No such file or + directory" when installing via easy_install.

(patch from Lorenz Quack) + + * Release the GIL while encrypting, decrypting, and hashing (but not + during initialization or finalization). + + * API changes: + + - Removed RandomPoolCompat and made Crypto.Util.randpool.RandomPool + a wrapper around Crypto.Random that emits a DeprecationWarning. + This is to discourage developers from attempting to provide + backwards compatibility for systems where there are NO strong + entropy sources available. + + - Added Crypto.Random.get_random_bytes(). This should allow people + to use something like this if they want backwards-compatibility: + + try: + from Crypto.Random import get_random_bytes + except ImportError: + try: + from os import urandom as get_random_bytes + except ImportError: + get_random_bytes = open("/dev/urandom", "rb").read + + - Implemented __ne__() on pubkey, which fixes the following broken + behaviour: + >>> pk.publickey() == pk.publickey() + True + >>> pk.publickey() != pk.publickey() + True + (patch from Lorenz Quack) + + - Block ciphers created with MODE_CTR can now operate on strings of + any size, rather than just multiples of the underlying cipher's + block size. + + - Crypto.Util.Counter objects now raise OverflowError when they wrap + around to zero. You can override this new behaviour by passing + allow_wraparound=True to Counter.new() + + +2.1.0alpha1 +=========== + + * This version supports Python versions 2.1 through 2.6. + + * Clarified copyright status of much of the existing code by tracking + down Andrew M. Kuchling, Barry A. Warsaw, Jeethu Rao, Joris Bontje, + Mark Moraes, Paul Swartz, Robey Pointer, and Wim Lewis and getting + their permission to clarify the license/public-domain status of their + contributions. Many thanks to all involved! + + * Replaced the test suite with a new, comprehensive package + (Crypto.SelfTest) that includes documentation about where its test + vectors came from, or how they were derived. + + Use "python setup.py test" to run the tests after building. + + * API changes: + + - Added Crypto.version_info, which from now on will contain version + information in a format similar to Python's sys.version_info. + + - Added a new random numbers API (Crypto.Random), and deprecated the + old one (Crypto.Util.randpool.RandomPool), which was misused more + often than not. + + The new API is used by invoking Crypto.Random.new() and then just + reading from the file-like object that is returned. + + CAVEAT: To maintain the security of the PRNG, you must call + Crypto.Random.atfork() in both the parent and the child processes + whenever you use os.fork(). Otherwise, the parent and child will + share copies of the same entropy pool, causing them to return the + same results! This is a limitation of Python, which does not + provide readily-accessible hooks to os.fork(). It's also a + limitation caused by the failure of operating systems to provide + sufficiently fast, trustworthy sources of cryptographically-strong + random numbers. + + - Crypto.PublicKey now raises ValueError/TypeError/RuntimeError + instead of the various custom "error" exceptions + + - Removed the IDEA and RC5 modules due to software patents. Debian + has been doing this for a while + + - Added Crypto.Random.random, a strong version of the standard Python + 'random' module. + + - Added Crypto.Util.Counter, providing fast counter implementations + for use with CTR-mode ciphers. + + * Bug fixes: + + - Fixed padding bug in SHA256; this resulted in bad digests whenever + (the number of bytes hashed) mod 64 == 55. + + - Fixed a 32-bit limitation on the length of messages the SHA256 module + could hash. + + - AllOrNothing: Fixed padding bug in digest() + + - Fixed a bad behaviour of the XOR cipher module: It would silently + truncate all keys to 32 bytes. Now it raises ValueError when the + key is too long. + + - DSA: Added code to enforce FIPS 186-2 requirements on the size of + the prime p + + - Fixed the winrandom module, which had been omitted from the build + process, causing security problems for programs that misuse RandomPool. + + - Fixed infinite loop when attempting to generate RSA keys with an + odd number of bits in the modulus. (Not that you should do that.) + + * Clarified the documentation for Crypto.Util.number.getRandomNumber. + + Confusingly, this function does NOT return N random bits; It returns + a random N-bit number, i.e. a random number between 2**(N-1) and (2**N)-1. + + Note that getRandomNumber is for internal use only and may be + renamed or removed in future releases. + + * Replaced RIPEMD.c with a new implementation (RIPEMD160.c) to + alleviate copyright concerns. + + * Replaced the DES/DES3 modules with ones based on libtomcrypt-1.16 to + alleviate copyright concerns. + + * Replaced Blowfish.c with a new implementation to alleviate copyright + concerns. + + * Added a string-XOR implementation written in C (Crypto.Util.strxor) + and used it to speed up Crypto.Hash.HMAC + + * Converted documentation to reStructured Text. + + * Added epydoc configuration Doc/epydoc-config + + * setup.py now emits a warning when building without GMP. + + * Added pct-speedtest.py to the source tree for doing performance + testing on the new code. + + * Cleaned up the code in several places. + + +2.0.1 +===== + + * Fix SHA256 and RIPEMD on AMD64 platform. + * Deleted Demo/ directory. + * Add PublicKey to Crypto.__all__ + + +2.0 +=== + + * Added SHA256 module contributed by Jeethu Rao, with test data + from Taylor Boon. + + * Fixed AES.c compilation problems with Borland C. + (Contributed by Jeethu Rao.) + + * Fix ZeroDivisionErrors on Windows, caused by the system clock + not having enough resolution. + + * Fix 2.1/2.2-incompatible use of (key not in dict), + pointed out by Ian Bicking. + + * Fix FutureWarning in Crypto.Util.randpool, noted by James P Rutledge. + + +1.9alpha6 +========= + + * Util.number.getPrime() would inadvertently round off the bit + size; if you asked for a 129-bit prime or 135-bit prime, you + got a 128-bit prime. + + * Added Util/test/prime_speed.py to measure the speed of prime + generation, and PublicKey/test/rsa_speed.py to measure + the speed of RSA operations. + + * Merged the _rsa.c and _dsa.c files into a single accelerator + module, _fastmath.c. + + * Speed improvements: Added fast isPrime() function to _fastmath, + cutting the time to generate a 1024-bit prime by a factor of 10. + Optimized the C version of RSA decryption to use a longer series + of operations that's roughly 3x faster than a single + exponentiation. (Contributed by Joris Bontje.) + + * Added support to RSA key objects for blinding and unblinding + data. (Contributed by Joris Bontje.) + + * Simplified RSA key generation: hard-wired the encryption + exponent to 65537 instead of generating a random prime; + generate prime factors in a loop until the product + is large enough. + + * Renamed cansign(), canencrypt(), hasprivate(), to + can_sign, can_encrypt, has_private. If people shriek about + this change very loudly, I'll add aliases for the old method + names that log a warning and call the new method. + + +1.9alpha5 +========= + + * Many randpool changes. RandomPool now has a + randomize(N:int) method that can be called to get N + bytes of entropy for the pool (N defaults to 0, + which 'fills up' the pool's entropy) KeyboardRandom + overloads this method. + + * Added src/winrand.c for Crypto.Util.winrandom and + now use winrandom for _randomize if possible. + (Calls Windows CryptoAPI CryptGenRandom) + + * Several additional places for stirring the pool, + capturing inter-event entropy when reading/writing, + stirring before and after saves. + + * RandomPool.add_event now returns the number of + estimated bits of added entropy, rather than the + pool entropy itself (since the pool entropy is + capped at the number of bits in the pool) + + * Moved termios code from KeyboardRandomPool into a + KeyboardEntry class, provided a version for Windows + using msvcrt. + + * Fix randpool.py crash on machines with poor timer resolution. + (Reported by Mark Moraes and others.) + + * If the GNU GMP library is available, two C extensions will be + compiled to speed up RSA and DSA operations. (Contributed by + Paul Swartz.) + + * DES3 with a 24-byte key was broken; now fixed. + (Patch by Philippe Frycia.) + + +1.9alpha4 +========= + + * Fix compilation problem on Windows. + + * HMAC.py fixed to work with pre-2.2 Pythons + + * setup.py now dies if built with Python 1.x + + +1.9alpha3 +========= + + * Fix a ref-counting bug that caused core dumps. + (Reported by Piers Lauder and an anonymous SF poster.) + + +1.9alpha2 +========= + + * (Backwards incompatible) The old Crypto.Hash.HMAC module is + gone, replaced by a copy of hmac.py from Python 2.2's standard + library. It will display a warning on interpreter versions + older than 2.2. + + * (Backwards incompatible) Restored the Crypto.Protocol package, + and modernized and tidied up the two modules in it, + AllOrNothing.py and Chaffing.py, renaming various methods + and changing the interface. + + * (Backwards incompatible) Changed the function names in + Crypto.Util.RFC1751. + + * Restored the Crypto.PublicKey package at user request. I + think I'll leave it in the package and warn about it in the + documentation. I hope that eventually I can point to + someone else's better public-key code, and at that point I + may insert warnings and begin the process of deprecating + this code. + + * Fix use of a Python 2.2 C function, replacing it with a + 2.1-compatible equivalent. (Bug report and patch by Andrew + Eland.) + + * Fix endianness bugs that caused test case failures on Sparc, + PPC, and doubtless other platforms. + + * Fixed compilation problem on FreeBSD and MacOS X. + + * Expanded the test suite (requires Sancho, from + http://www.mems-exchange.org/software/sancho/) + + * Added lots of docstrings, so 'pydoc Crypto' now produces + helpful output. (Open question: maybe *all* of the documentation + should be moved into docstrings?) + + * Make test.py automatically add the build/* directory to sys.path. + + * Removed 'inline' declaration from C functions. Some compilers + don't support it, and Python's pyconfig.h no longer tells you whether + it's supported or not. After this change, some ciphers got slower, + but others got faster. + + * The C-level API has been changed to reduce the amount of + memory-to-memory copying. This makes the code neater, but + had ambiguous performance effects; again, some ciphers got slower + and others became faster. Probably this is due to my compiler + optimizing slightly worse or better as a result. + + * Moved C source implementations into src/ from block/, hash/, + and stream/. Having Hash/ and hash/ directories causes problems + on case-insensitive filesystems such as Mac OS. + + * Cleaned up the C code for the extensions. + + +1.9alpha1 +========= + + * Added Crypto.Cipher.AES. + + * Added the CTR mode and the variable-sized CFB mode from the + NIST standard on feedback modes. + + * Removed Diamond, HAVAL, MD5, Sapphire, SHA, and Skipjack. MD5 + and SHA are included with Python; the others are all of marginal + usefulness in the real world. + + * Renamed the module-level constants ECB, CFB, &c., to MODE_ECB, + MODE_CFB, as part of making the block encryption modules + compliant with PEP 272. (I'm not sure about this change; + if enough users complain about it, I might back it out.) + + * Made the hashing modules compliant with PEP 247 (not backward + compatible -- the major changes are that the constructor is now + MD2.new and not MD2.MD2, and the size of the digest is now + given as 'digest_size', not 'digestsize'. + + * The Crypto.PublicKey package is no longer installed; the + interfaces are all wrong, and I have no idea what the right + interfaces should be. + + +1.1alpha2 +========= + * Most importantly, the distribution has been broken into two +parts: exportable, and export-controlled. The exportable part +contains all the hashing algorithms, signature-only public key +algorithms, chaffing & winnowing, random number generation, various +utility modules, and the documentation. + + The export-controlled part contains public-key encryption +algorithms such as RSA and ElGamal, and bulk encryption algorithms +like DES, IDEA, or Skipjack. Getting this code still requires that +you go through an access control CGI script, and denies you access if +you're outside the US or Canada. + + * Added the RIPEMD hashing algorithm. (Contributed by +Hirendra Hindocha.) + + * Implemented the recently declassified Skipjack block +encryption algorithm. My implementation runs at 864 K/sec on a +PII/266, which isn't particularly fast, but you're probably better off +using another algorithm anyway. :) + + * A simple XOR cipher has been added, mostly for use by the +chaffing/winnowing code. (Contributed by Barry Warsaw.) + + * Added Protocol.Chaffing and Hash.HMAC.py. (Contributed by +Barry Warsaw.) + + Protocol.Chaffing implements chaffing and winnowing, recently +proposed by R. Rivest, which hides a message (the wheat) by adding +many noise messages to it (the chaff). The chaff can be discarded by +the receiver through a message authentication code. The neat thing +about this is that it allows secret communication without actually +having an encryption algorithm, and therefore this falls within the +exportable subset. + + * Tidied up randpool.py, and removed its use of a block +cipher; this makes it work with only the export-controlled subset +available. + + * Various renamings and reorganizations, mostly internal. + + +1.0.2 +===== + + * Changed files to work with Python 1.5; everything has been +re-arranged into a hierarchical package. (Not backward compatible.) +The package organization is: +Crypto. + Hash. + MD2, MD4, MD5, SHA, HAVAL + Cipher. + ARC2, ARC4, Blowfish, CAST, DES, DES3, Diamond, + IDEA, RC5, Sapphire + PublicKey. + DSA, ElGamal, qNEW, RSA + Util. + number, randpool, RFC1751 + + Since this is backward-incompatible anyway, I also changed +module names from all lower-case to mixed-case: diamond -> Diamond, +rc5 -> RC5, etc. That had been an annoying inconsistency for a while. + + * Added CAST5 module contributed by . + + * Added qNEW digital signature algorithm (from the digisign.py +I advertised a while back). (If anyone would like to suggest new +algorithms that should be implemented, please do; I think I've got +everything that's really useful at the moment, but...) + + * Support for keyword arguments has been added. This allowed +removing the obnoxious key handling for Diamond and RC5, where the +first few bytes of the key indicated the number of rounds to use, and +various other parameters. Now you need only do something like: + +from Crypto.Cipher import RC5 +obj = RC5.new(key, RC5.ECB, rounds=8) + +(Not backward compatible.) + + * Various function names have been changed, and parameter +names altered.

This +documentation assumes you have some basic knowledge about the Python +language, but not necessarily about cryptography. + +.. contents:: + +Introduction +------------------- + +Design Goals +=================== + +The Python cryptography toolkit is intended to provide a reliable and +stable base for writing Python programs that require cryptographic +functions. + +A central goal has been to provide a simple, consistent interface for +similar classes of algorithms. For example, all block cipher objects +have the same methods and return values, and support the same feedback +modes. Hash functions have a different interface, but it too is +consistent over all the hash functions available. Some of these +interfaces have been codified as Python Enhancement Proposal +documents, as PEP 247, "API for Cryptographic Hash Functions", and +PEP 272, "API for Block Encryption Algorithms". + +This is intended to make it easy to replace old algorithms with newer, +more secure ones. If you're given a bit of portably-written Python +code that uses the DES encryption algorithm, you should be able to use +AES instead by simply changing ``from Crypto.Cipher import DES`` to +``from Crypto.Cipher import AES``, and changing all references to +``DES.new()`` to ``AES.new()``. It's also fairly simple to +write your own modules that mimic this interface, thus letting you use +combinations or permutations of algorithms. + +Some modules are implemented in C for performance; others are written +in Python for ease of modification. Generally, low-level functions +like ciphers and hash functions are written in C, while less +speed-critical functions have been written in Python. This division +may change in future releases. When speeds are quoted in this +document, they were measured on a 500 MHz Pentium II running Linux. +The exact speeds will obviously vary with different machines, +different compilers, and the phase of the moon, but they provide a +crude basis for comparison. Currently the cryptographic +implementations are acceptably fast, but not spectacularly good. I +welcome any suggestions or patches for faster code. + +I have placed the code under no restrictions; you can redistribute the +code freely or commercially, in its original form or with any +modifications you make, subject to whatever local laws may apply in your +jurisdiction. Note that you still have to come to some agreement with +the holders of any patented algorithms you're using. If you're +intensively using these modules, please tell me about it; there's little +incentive for me to work on this package if I don't know of anyone using +it. + +I also make no guarantees as to the usefulness, correctness, or legality +of these modules, nor does their inclusion constitute an endorsement of +their effectiveness. Many cryptographic algorithms are patented; +inclusion in this package does not necessarily mean you are allowed to +incorporate them in a product and sell it. Some of these algorithms may +have been cryptanalyzed, and may no longer be secure. While I will +include commentary on the relative security of the algorithms in the +sections entitled "Security Notes", there may be more recent analyses +I'm not aware of. (Or maybe I'm just clueless.) If you're implementing +an important system, don't just grab things out of a toolbox and put +them together; do some research first. On the other hand, if you're +just interested in keeping your co-workers or your relatives out of your +files, any of the components here could be used. + +This document is very much a work in progress. If you have any +questions, comments, complaints, or suggestions, please send them to me. + +Acknowledgements +================================================== + +Much of the code that actually implements the various cryptographic +algorithms was not written by me. I'd like to thank all the people who +implemented them, and released their work under terms which allowed me +to use their code. These individuals are credited in the relevant +chapters of this documentation. Bruce Schneier's book +:title-reference:`Applied Cryptography` was also very useful in writing this toolkit; I highly +recommend it if you're interested in learning more about cryptography. + +Good luck with your cryptography hacking! + + +Crypto.Hash: Hash Functions +-------------------------------------------------- + +Hash functions take arbitrary strings as input, and produce an output +of fixed size that is dependent on the input; it should never be +possible to derive the input data given only the hash function's +output. One simple hash function consists of simply adding together +all the bytes of the input, and taking the result modulo 256. For a +hash function to be cryptographically secure, it must be very +difficult to find two messages with the same hash value, or to find a +message with a given hash value. The simple additive hash function +fails this criterion miserably and the hash functions described below +meet this criterion (as far as we know). Examples of +cryptographically secure hash functions include MD2, MD5, and SHA1. + +Hash functions can be used simply as a checksum, or, in association with a +public-key algorithm, can be used to implement digital signatures. + +The hashing algorithms currently implemented are: + +============= ============= ======== +Hash function Digest length Security +============= ============= ======== +MD2 128 bits Insecure, do not use +MD4 128 bits Insecure, do not use +MD5 128 bits Insecure, do not use +RIPEMD 160 bits Secure.

The HMAC module is +a copy of Python 2.2's module, and works on Python 2.1 as well. +HMAC's security depends on the cryptographic strength of the key handed to it, +and on the underlying hashing method used. HMAC-MD5 and HMAC-SHA1 are used in +IPSEC and TLS. + +All hashing modules with the exception of HMAC share the same interface. +After importing a given hashing module, call the ``new()`` function to create +a new hashing object. You can now feed arbitrary strings into the object +with the ``update()`` method, and can ask for the hash value at +any time by calling the ``digest()`` or ``hexdigest()`` +methods. The ``new()`` function can also be passed an optional +string parameter that will be immediately hashed into the object's +state. + +To create a HMAC object, call HMAC's ```new()`` function with the key (as +a string or bytes object) to be used, an optional message, and the hash +function to use. HMAC defaults to using MD5. This is not a secure default, +please use SHA256 or better instead in new implementations. + +Hash function modules define one variable: + +**digest_size**: +An integer value; the size of the digest +produced by the hashing objects. You could also obtain this value by +creating a sample object, and taking the length of the digest string +it returns, but using ``digest_size`` is faster. + +The methods for hashing objects are always the following: + +**copy()**: +Return a separate copy of this hashing object. An ``update`` to +this copy won't affect the original object. + + +**digest()**: +Return the hash value of this hashing object, as a string containing +8-bit data. The object is not altered in any way by this function; +you can continue updating the object after calling this function. +Python 3.x: digest() returns a bytes object + +**hexdigest()**: +Return the hash value of this hashing object, as a string containing +the digest data as hexadecimal digits. The resulting string will be +twice as long as that returned by ``digest()``. The object is not +altered in any way by this function; you can continue updating the +object after calling this function. + + +**update(arg)**: +Update this hashing object with the string ``arg``. +Python 3.x: The passed argument must be an object interpretable as +a buffer of bytes + + +Here's an example, using the SHA-256 algorithm:: + + >>> from Crypto.Hash import SHA256 + >>> m = SHA256.new() + >>> m.update('abc') + >>> m.digest() + '\xbax\x16\xbf\x8f\x01\xcf\xeaAA@\xde]\xae"#\xb0\x03a\xa3\x96\x17z\x9c\xb4\x10\xffa\xf2\x00\x15\xad' + >>> m.hexdigest() + 'ba7816bf8f01cfea414140de5dae2223b00361a396177a9cb410ff61f20015ad' + +Here's an example of using HMAC:: + + >>> from Crypto.Hash import HMAC, SHA256 + >>> m = HMAC.new('Please do not use this key in your code, with sugar on top', + '', SHA256) + >>> m.update('abc') + >>> m.digest() + 'F\xaa\x83\t\x97<\x8c\x12\xff\xe8l\xca:\x1d\xb4\xfc7\xfa\x84tK-\xb0\x00v*\xc2\x90\x19\xaa\xfaz' + >>> m.hexdigest() + '46aa8309973c8c12ffe86cca3a1db4fc37fa84744b2db000762ac29019aafa7a' + +Security Notes +========================== + +Hashing algorithms are broken by developing an algorithm to compute a +string that produces a given hash value, or to find two messages that +produce the same hash value. Consider an example where Alice and Bob +are using digital signatures to sign a contract. Alice computes the +hash value of the text of the contract and signs the hash value with +her private key. Bob could then compute a different contract that has +the same hash value, and it would appear that Alice signed that bogus +contract; she'd have no way to prove otherwise. Finding such a +message by brute force takes ``pow(2, b-1)`` operations, where the +hash function produces *b*-bit hashes. + +If Bob can only find two messages with the same hash value but can't +choose the resulting hash value, he can look for two messages with +different meanings, such as "I will mow Bob's lawn for $10" and "I owe +Bob $1,000,000", and ask Alice to sign the first, innocuous contract. +This attack is easier for Bob, since finding two such messages by brute +force will take ``pow(2, b/2)`` operations on average. However, +Alice can protect herself by changing the protocol; she can simply +append a random string to the contract before hashing and signing it; +the random string can then be kept with the signature. + +Some of the algorithms implemented here have been completely broken. +The MD2, MD4 and MD5 hash functions are widely considered insecure +hash functions, as it has been proven that meaningful hash collisions +can be generated for them, in the case of MD4 and MD5 in mere seconds. +MD2 is rather slow at 1250 K/sec. MD4 is faster at 44,500 K/sec. +MD5 is a strengthened version of MD4 with four rounds; beginning in 2004, +a series of attacks were discovered and it's now possible to create pairs +of files that result in the same MD5 hash. The MD5 +implementation is moderately well-optimized and thus faster on x86 +processors, running at 35,500 K/sec. MD5 may even be faster than MD4, +depending on the processor and compiler you use. +MD5 is still supported for compatibility with existing protocols, but +implementors should use SHA256 in new software because there are no known +attacks against SHA256. + +All the MD* algorithms produce 128-bit hashes. +SHA1 produces a 160-bit hash. Because of recent theoretical attacks against SHA1, +NIST recommended phasing out use of SHA1 by 2010. +SHA256 produces a larger 256-bit hash, and there are no known attacks against it. +It operates at 10,500 K/sec. +RIPEMD has a 160-bit output, the same output size as SHA1, and operates at 17,600 +K/sec. + +Credits +=============== + +The MD2 and MD4 implementations were written by A.M. Kuchling, and the MD5 +code was implemented by Colin Plumb. The SHA1 code was originally written by +Peter Gutmann. The RIPEMD160 code as of version 2.1.0 was written by Dwayne +Litzenberger. The SHA256 code was written by Tom St. Denis and is part of the +LibTomCrypt library (http://www.libtomcrypt.org/); it was adapted for the +toolkit by Jeethu Rao and Taylor Boon. + + + +Crypto.Cipher: Encryption Algorithms +-------------------------------------------------- + +Encryption algorithms transform their input data, or **plaintext**, +in some way that is dependent on a variable **key**, producing +**ciphertext**. This transformation can easily be reversed, if (and, +hopefully, only if) one knows the key. The key can be varied by the +user or application and chosen from some very large space of possible +keys. + +For a secure encryption algorithm, it should be very difficult to +determine the original plaintext without knowing the key; usually, no +clever attacks on the algorithm are known, so the only way of breaking +the algorithm is to try all possible keys. Since the number of possible +keys is usually of the order of 2 to the power of 56 or 128, this is not +a serious threat, although 2 to the power of 56 is now considered +insecure in the face of custom-built parallel computers and distributed +key guessing efforts. + +**Block ciphers** take multibyte inputs of a fixed size +(frequently 8 or 16 bytes long) and encrypt them. Block ciphers can +be operated in various modes. The simplest is Electronic Code Book +(or ECB) mode. In this mode, each block of plaintext is simply +encrypted to produce the ciphertext. This mode can be dangerous, +because many files will contain patterns greater than the block size; +for example, the comments in a C program may contain long strings of +asterisks intended to form a box. All these identical blocks will +encrypt to identical ciphertext; an adversary may be able to use this +structure to obtain some information about the text. + +To eliminate this weakness, there are various feedback modes in which +the plaintext is combined with the previous ciphertext before +encrypting; this eliminates any repetitive structure in the +ciphertext. + +One mode is Cipher Block Chaining (CBC mode); another is Cipher +FeedBack (CFB mode). CBC mode still encrypts in blocks, and thus is +only slightly slower than ECB mode. CFB mode encrypts on a +byte-by-byte basis, and is much slower than either of the other two +modes. The chaining feedback modes require an initialization value to +start off the encryption; this is a string of the same length as the +ciphering algorithm's block size, and is passed to the ``new()`` +function. + +The currently available block ciphers are listed in the following table, +and are in the ``Crypto.Cipher`` package: + +================= ============================ +Cipher Key Size/Block Size +================= ============================ +AES 16, 24, or 32 bytes/16 bytes +ARC2 Variable/8 bytes +Blowfish Variable/8 bytes +CAST Variable/8 bytes +DES 8 bytes/8 bytes +DES3 (Triple DES) 16 bytes/8 bytes +================= ============================ + + +In a strict formal sense, **stream ciphers** encrypt data bit-by-bit; +practically, stream ciphers work on a character-by-character basis. +Stream ciphers use exactly the same interface as block ciphers, with a block +length that will always be 1; this is how block and stream ciphers can be +distinguished. +The only feedback mode available for stream ciphers is ECB mode. + +The currently available stream ciphers are listed in the following table: + +======= ========= +Cipher Key Size +======= ========= + ARC4 Variable + XOR Variable +======= ========= + +ARC4 is short for "Alleged RC4". In September of 1994, someone posted +C code to both the Cypherpunks mailing list and to the Usenet +newsgroup ``sci.crypt``, claiming that it implemented the RC4 +algorithm. This claim turned out to be correct. Note that there's a +damaging class of weak RC4 keys; this module won't warn you about such keys. + +.. % XXX are there other analyses of RC4? + +A similar anonymous posting was made for Alleged RC2 in January, 1996. + +An example usage of the DES module:: + + >>> from Crypto.Cipher import DES + >>> obj=DES.new('abcdefgh', DES.MODE_ECB) + >>> plain="Guido van Rossum is a space alien." + >>> len(plain) + 34 + >>> obj.encrypt(plain) + Traceback (innermost last): + File "", line 1, in ? + ValueError: Strings for DES must be a multiple of 8 in length + >>> ciph=obj.encrypt(plain+'XXXXXX') + >>> ciph + '\021,\343Nq\214DY\337T\342pA\372\255\311s\210\363,\300j\330\250\312\347\342I\3215w\03561\303dgb/\006' + >>> obj.decrypt(ciph) + 'Guido van Rossum is a space alien.XXXXXX' + +All cipher algorithms share a common interface. After importing a +given module, there is exactly one function and two variables +available. + +**new(key, mode[, IV])**: +Returns a ciphering object, using ``key`` and feedback mode +``mode``. +If ``mode`` is ``MODE_CBC`` or ``MODE_CFB``, ``IV`` must be provided, + and must be a string of the same length as the block size. +Some algorithms support additional keyword arguments to this function; see +the "Algorithm-specific Notes for Encryption Algorithms" section below for the details. +Python 3.x: ```mode`` is a string object; ```key``` and ```IV``` must be +objects interpretable as a buffer of bytes. + +**block_size**: +An integer value; the size of the blocks encrypted by this module. +Strings passed to the ``encrypt`` and ``decrypt`` functions +must be a multiple of this length. For stream ciphers, +``block_size`` will be 1. + +**key_size**: +An integer value; the size of the keys required by this module. If +``key_size`` is zero, then the algorithm accepts arbitrary-length +keys. You cannot pass a key of length 0 (that is, the null string +``""`` as such a variable-length key. + +All cipher objects have at least three attributes: + +**block_size**: +An integer value equal to the size of the blocks encrypted by this object. +Identical to the module variable of the same name. + + +**IV**: +Contains the initial value which will be used to start a cipher +feedback mode. After encrypting or decrypting a string, this value +will reflect the modified feedback text; it will always be one block +in length. It is read-only, and cannot be assigned a new value. +Python 3.x: ```IV``` is a bytes object. + +**key_size**: +An integer value equal to the size of the keys used by this object. If +``key_size`` is zero, then the algorithm accepts arbitrary-length +keys. For algorithms that support variable length keys, this will be 0. +Identical to the module variable of the same name. + + +All ciphering objects have the following methods: + +**decrypt(string)**: +Decrypts ``string``, using the key-dependent data in the object, and +with the appropriate feedback mode. The string's length must be an exact +multiple of the algorithm's block size. Returns a string containing +the plaintext. +Python 3.x: decrypt() will return a bytes object. + +Note: Do not use the same cipher object for both encryption an +decryption, since both operations share the same IV buffer, so the results +will probably not be what you expect. + + +**encrypt(string)**: +Encrypts a non-null ``string``, using the key-dependent data in the +object, and with the appropriate feedback mode. The string's length +must be an exact multiple of the algorithm's block size; for stream +ciphers, the string can be of any length. Returns a string containing +the ciphertext. +Python 3.x: ```string``` must be an object interpretable as a buffer of bytes. +encrypt() will return a bytes object. + +Note: Do not use the same cipher object for both encryption an +decryption, since both operations share the same IV buffer, so the results +will probably not be what you expect. + + +Security Notes +======================= + +Encryption algorithms can be broken in several ways. If you have some +ciphertext and know (or can guess) the corresponding plaintext, you can +simply try every possible key in a **known-plaintext** attack. Or, it +might be possible to encrypt text of your choice using an unknown key; +for example, you might mail someone a message intending it to be +encrypted and forwarded to someone else. This is a +**chosen-plaintext** attack, which is particularly effective if it's +possible to choose plaintexts that reveal something about the key when +encrypted. + +Stream ciphers are only secure if any given key is never used twice. +If two (or more) messages are encrypted using the same key in a stream +cipher, the cipher can be broken fairly easily. + +DES (5100 K/sec) has a 56-bit key; this is starting to become too small +for safety. It has been shown in 2009 that a ~$10,000 machine can break +DES in under a day on average. NIST has withdrawn FIPS 46-3 in 2005. +DES3 (1830 K/sec) uses three DES encryptions for greater security and a 112-bit +or 168-bit key, but is correspondingly slower. Attacks against DES3 are +not currently feasible, and it has been estimated to be useful until 2030. +Bruce Schneier endorses DES3 for its security because of the decades of +study applied against it. It is, however, slow. + +There are no known attacks against Blowfish (9250 K/sec) or CAST (2960 K/sec), +but they're all relatively new algorithms and there hasn't been time for much +analysis to be performed; use them for serious applications only after careful +research. + +pycrypto implements CAST with up to 128 bits key length (CAST-128). This +algorithm is considered obsoleted by CAST-256. CAST is patented by Entrust +Technologies and free for non-commercial use. + +Bruce Schneier recommends his newer Twofish algorithm over Blowfish where +a fast, secure symmetric cipher is desired. Twofish was an AES candidate. It +is slightly slower than Rijndael (the chosen algorithm for AES) for 128-bit +keys, and slightly faster for 256-bit keys. + +AES, the Advanced Encryption Standard, was chosen by the US National +Institute of Standards and Technology from among 6 competitors, and is +probably your best choice. It runs at 7060 K/sec, so it's among the +faster algorithms around. + +ARC4 ("Alleged" RC4) (8830 K/sec) has been weakened. Specifically, it has been +shown that the first few bytes of the ARC4 keystream are strongly non-random, +leaking information about the key. When the long-term key and nonce are merely +concatenated to form the ARC4 key, such as is done in WEP, this weakness can be +used to discover the long-term key by observing a large number of messages +encrypted with this key. +Because of these possible related-key attacks, ARC4 should only be used with +keys generated by a strong RNG, or from a source of sufficiently uncorrelated +bits, such as the output of a hash function. +A further possible defense is to discard the initial portion of the keystream. +This altered algorithm is called RC4-drop(n). +While ARC4 is in wide-spread use in several protocols, its use in new protocols +or applications is discouraged. + +ARC2 ("Alleged" RC2) is vulnerable to a related-key attack, 2^34 chosen +plaintexts are needed. +Because of these possible related-key attacks, ARC2 should only be used with +keys generated by a strong RNG, or from a source of sufficiently uncorrelated +bits, such as the output of a hash function. + +Credits +============= + +The code for Blowfish was written from scratch by Dwayne Litzenberger, based +on a specification by Bruce Schneier, who also invented the algorithm; the +Blowfish algorithm has been placed in the public domain and can be used +freely. (See http://www.schneier.com/paper-blowfish-fse.html for more +information about Blowfish.) The CAST implementation was written by Wim Lewis. +The DES implementation uses libtomcrypt, which was written by Tom St Denis. + +The Alleged RC4 code was posted to the ``sci.crypt`` newsgroup by an +unknown party, and re-implemented by A.M. Kuchling. + + +Crypto.Protocol: Various Protocols +-------------------------------------------------- + +Crypto.Protocol.AllOrNothing +========================================== + +This module implements all-or-nothing package transformations. +An all-or-nothing package transformation is one in which some text is +transformed into message blocks, such that all blocks must be obtained before +the reverse transformation can be applied. Thus, if any blocks are corrupted +or lost, the original message cannot be reproduced. + +An all-or-nothing package transformation is not encryption, although a block +cipher algorithm is used. The encryption key is randomly generated and is +extractable from the message blocks. + +**AllOrNothing(ciphermodule, mode=None, IV=None)**: +Class implementing the All-or-Nothing package transform. + +``ciphermodule`` is a module implementing the cipher algorithm to +use. Optional arguments ``mode`` and ``IV`` are passed directly +through to the ``ciphermodule.new()`` method; they are the +feedback mode and initialization vector to use. All three arguments +must be the same for the object used to create the digest, and to +undigest'ify the message blocks. + +The module passed as ``ciphermodule`` must provide the PEP 272 +interface. An encryption key is randomly generated automatically when +needed. + + +The methods of the ``AllOrNothing`` class are: + +**digest(text)**: +Perform the All-or-Nothing package transform on the +string ``text``. Output is a list of message blocks describing the +transformed text, where each block is a string of bit length equal +to the cipher module's block_size. + + +**undigest(mblocks)**: +Perform the reverse package transformation on a list of message +blocks. Note that the cipher module used for both transformations +must be the same. ``mblocks`` is a list of strings of bit length +equal to ``ciphermodule``'s block_size. The output is a string object. + + + +Crypto.Protocol.Chaffing +================================================== + +Winnowing and chaffing is a technique for enhancing privacy without requiring +strong encryption. In short, the technique takes a set of authenticated +message blocks (the wheat) and adds a number of chaff blocks which have +randomly chosen data and MAC fields. This means that to an adversary, the +chaff blocks look as valid as the wheat blocks, and so the authentication +would have to be performed on every block. By tailoring the number of chaff +blocks added to the message, the sender can make breaking the message +computationally infeasible. There are many other interesting properties of +the winnow/chaff technique. + +For example, say Alice is sending a message to Bob. She packetizes the +message and performs an all-or-nothing transformation on the packets. Then +she authenticates each packet with a message authentication code (MAC). The +MAC is a hash of the data packet, and there is a secret key which she must +share with Bob (key distribution is an exercise left to the reader). She then +adds a serial number to each packet, and sends the packets to Bob. + +Bob receives the packets, and using the shared secret authentication key, +authenticates the MACs for each packet. Those packets that have bad MACs are +simply discarded. The remainder are sorted by serial number, and passed +through the reverse all-or-nothing transform. The transform means that an +eavesdropper (say Eve) must acquire all the packets before any of the data can +be read. If even one packet is missing, the data is useless. + +There's one twist: by adding chaff packets, Alice and Bob can make Eve's job +much harder, since Eve now has to break the shared secret key, or try every +combination of wheat and chaff packet to read any of the message. The cool +thing is that Bob doesn't need to add any additional code; the chaff packets +are already filtered out because their MACs don't match (in all likelihood -- +since the data and MACs for the chaff packets are randomly chosen it is +possible, but very unlikely that a chaff MAC will match the chaff data). And +Alice need not even be the party adding the chaff! She could be completely +unaware that a third party, say Charles, is adding chaff packets to her +messages as they are transmitted. + +**Chaff(factor=1.0, blocksper=1)**: +Class implementing the chaff adding algorithm. +``factor`` is the number of message blocks +to add chaff to, expressed as a percentage between 0.0 and 1.0; the default value is 1.0. +``blocksper`` is the number of chaff blocks to include for each block +being chaffed, and defaults to 1. The default settings +add one chaff block to every +message block. By changing the defaults, you can adjust how +computationally difficult it could be for an adversary to +brute-force crack the message. The difficulty is expressed as:: + + pow(blocksper, int(factor * number-of-blocks)) + +For ease of implementation, when ``factor`` < 1.0, only the first +``int(factor*number-of-blocks)`` message blocks are chaffed. + +``Chaff`` instances have the following methods: + +**chaff(blocks)**: +Add chaff to message blocks. ``blocks`` is a list of 3-tuples of the +form ``(serial-number, data, MAC)``. + +Chaff is created by choosing a random number of the same +byte-length as ``data``, and another random number of the same +byte-length as ``MAC``. The message block's serial number is placed +on the chaff block and all the packet's chaff blocks are randomly +interspersed with the single wheat block. This method then +returns a list of 3-tuples of the same form. Chaffed blocks will +contain multiple instances of 3-tuples with the same serial +number, but the only way to figure out which blocks are wheat and +which are chaff is to perform the MAC hash and compare values. + + + +Crypto.PublicKey: Public-Key Algorithms +-------------------------------------------------- + +So far, the encryption algorithms described have all been *private key* +ciphers. The same key is used for both encryption and decryption +so all correspondents must know it. This poses a problem: you may +want encryption to communicate sensitive data over an insecure +channel, but how can you tell your correspondent what the key is? You +can't just e-mail it to her because the channel is insecure. One +solution is to arrange the key via some other way: over the phone or +by meeting in person. + +Another solution is to use **public-key** cryptography. In a public +key system, there are two different keys: one for encryption and one for +decryption. The encryption key can be made public by listing it in a +directory or mailing it to your correspondent, while you keep the +decryption key secret. Your correspondent then sends you data encrypted +with your public key, and you use the private key to decrypt it. While +the two keys are related, it's very difficult to derive the private key +given only the public key; however, deriving the private key is always +possible given enough time and computing power. This makes it very +important to pick keys of the right size: large enough to be secure, but +small enough to be applied fairly quickly. + +Many public-key algorithms can also be used to sign messages; simply +run the message to be signed through a decryption with your private +key key. Anyone receiving the message can encrypt it with your +publicly available key and read the message. Some algorithms do only +one thing, others can both encrypt and authenticate. + +The currently available public-key algorithms are listed in the +following table: + +============= ========================================== +Algorithm Capabilities +============= ========================================== +RSA Encryption, authentication/signatures +ElGamal Encryption, authentication/signatures +DSA Authentication/signatures +============= ========================================== + +Many of these algorithms are patented. Before using any of them in a +commercial product, consult a patent attorney; you may have to arrange +a license with the patent holder. + +An example of using the RSA module to sign a message:: + + >>> from Crypto.Hash import MD5 + >>> from Crypto.PublicKey import RSA + >>> from Crypto import Random + >>> rng = Random.new().read + >>> RSAkey = RSA.generate(2048, rng) # This will take a while... + >>> hash = MD5.new(plaintext).digest() + >>> signature = RSAkey.sign(hash, rng) + >>> signature # Print what an RSA sig looks like--you don't really care. + ('\021\317\313\336\264\315' ...,) + >>> RSAkey.verify(hash, signature) # This sig will check out + 1 + >>> RSAkey.verify(hash[:-1], signature)# This sig will fail + 0 + +Public-key modules make the following functions available: + +**construct(tuple)**: +Constructs a key object from a tuple of data. This is +algorithm-specific; look at the source code for the details. (To be +documented later.) + +**generate(size, randfunc, progress_func=None, e=65537)**: +Generate a fresh public/private key pair. ``size`` is a +algorithm-dependent size parameter, usually measured in bits; the +larger it is, the more difficult it will be to break the key. Safe +key sizes vary from algorithm to algorithm; you'll have to research +the question and decide on a suitable key size for your application. +An N-bit keys can encrypt messages up to N-1 bits long. + +``randfunc`` is a random number generation function; it should +accept a single integer ``N`` and return a string of random data +``N`` bytes long. You should always use a cryptographically secure +random number generator, such as the one defined in the +``Crypto.Random`` module; **don't** just use the +current time and the ``random`` module. + +``progress_func`` is an optional function that will be called with a short +string containing the key parameter currently being generated; it's +useful for interactive applications where a user is waiting for a key +to be generated. + +``e`` is the public RSA exponent, and must be an odd positive integer. +It is typically a small number with very few ones in its binary representation. +The default value 65537 (=0b10000000000000001) is a safe choice: other +common values are 5, 7, 17, and 257. Exponent 3 is also widely used, +but it requires very special care when padding the message. + +If you want to interface with some other program, you will have to know +the details of the algorithm being used; this isn't a big loss. If you +don't care about working with non-Python software, simply use the +``pickle`` module when you need to write a key or a signature to a +file. It's portable across all the architectures that Python supports, +and it's simple to use. + +In case interoperability were important, RSA key objects can be exported +and imported in two standard formats: the DER binary encoding specified in +PKCS#1 (see RFC3447) or the ASCII textual encoding specified by the +old Privacy Enhanced Mail services (PEM, see RFC1421). + + +The RSA module makes the following function available for importing keys: + +**importKey(externKey)**: +Import an RSA key (pubic or private) encoded as a string ``externKey``. +The key can follow either the PKCS#1/DER format (binary) or the PEM format +(7-bit ASCII). + +For instance: + >>> from Crypto.PublicKey import RSA + >>> f = open("mykey.pem") + >>> RSAkey = RSA.importKey(f.read()) + >>> if RSAkey.has_private(): print "Private key" + +Every RSA object supports the following method to export itself: + +**exportKey(format='PEM')**: +Return the key encoded as a string, according to the specified ``format``: +``'PEM'`` (default) or ``'DER'`` (also known as PKCS#1). + +For instance: + >>> from Crypto.PublicKey import RSA + >>> from Crypto import Random + >>> rng = Random.new().read + >>> RSAkey = RSA.generate(1024, rng) + >>> f = open("keyPrivate.der","w+") + >>> f.write(RSAkey.exportKey("DER")) + >>> f.close() + >>> f = open("keyPublic.pem","w+") + >>> f.write(RSAkey.publickey().exportKey("PEM")) + >>> f.close() + +Public-key objects always support the following methods. Some of them +may raise exceptions if their functionality is not supported by the +algorithm. + + +**can_blind()**: +Returns true if the algorithm is capable of blinding data; +returns false otherwise. + + +**can_encrypt()**: +Returns true if the algorithm is capable of encrypting and decrypting +data; returns false otherwise. To test if a given key object can encrypt +data, use ``key.can_encrypt() and key.has_private()``. + + +**can_sign()**: +Returns true if the algorithm is capable of signing data; returns false +otherwise. To test if a given key object can sign data, use +``key.can_sign() and key.has_private()``. + + +**decrypt(tuple)**: +Decrypts ``tuple`` with the private key, returning another string. +This requires the private key to be present, and will raise an exception +if it isn't present. It will also raise an exception if ``string`` is +too long. + + +**encrypt(string, K)**: +Encrypts ``string`` with the private key, returning a tuple of +strings; the length of the tuple varies from algorithm to algorithm. +``K`` should be a string of random data that is as long as +possible. Encryption does not require the private key to be present +inside the key object. It will raise an exception if ``string`` is +too long. For ElGamal objects, the value of ``K`` expressed as a +big-endian integer must be relatively prime to ``self.p-1``; an +exception is raised if it is not. +Python 3.x: ```string``` must be an object interpretable as a buffer of bytes. + + +**has_private()**: +Returns true if the key object contains the private key data, which +will allow decrypting data and generating signatures. +Otherwise this returns false. + + +**publickey()**: +Returns a new public key object that doesn't contain the private key +data. + + +**sign(string, K)**: +Sign ``string``, returning a signature, which is just a tuple; in +theory the signature may be made up of any Python objects at all; in +practice they'll be either strings or numbers. ``K`` should be a +string of random data that is as long as possible. Different algorithms +will return tuples of different sizes. ``sign()`` raises an +exception if ``string`` is too long. For ElGamal objects, the value +of ``K`` expressed as a big-endian integer must be relatively prime to +``self.p-1``; an exception is raised if it is not. +Python 3.x: ```string``` must be an object interpretable as a buffer of bytes. + + +**size()**: +Returns the maximum size of a string that can be encrypted or signed, +measured in bits. String data is treated in big-endian format; the most +significant byte comes first. (This seems to be a **de facto** standard +for cryptographical software.) If the size is not a multiple of 8, then +some of the high order bits of the first byte must be zero. Usually +it's simplest to just divide the size by 8 and round down. + + +**verify(string, signature)**: +Returns true if the signature is valid, and false otherwise. +``string`` is not processed in any way; ``verify`` does +not run a hash function over the data, but you can easily do that yourself. +Python 3.x: ```string``` must be an object interpretable as a buffer of bytes. + + +The ElGamal and DSA algorithms +================================================== + +For RSA, the ``K`` parameters are unused; if you like, you can just +pass empty strings. The ElGamal and DSA algorithms require a real +``K`` value for technical reasons; see Schneier's book for a detailed +explanation of the respective algorithms. This presents a possible +hazard that can inadvertently reveal the private key. Without going into the +mathematical details, the danger is as follows. ``K`` is never derived +or needed by others; theoretically, it can be thrown away once the +encryption or signing operation is performed. However, revealing +``K`` for a given message would enable others to derive the secret key +data; worse, reusing the same value of ``K`` for two different +messages would also enable someone to derive the secret key data. An +adversary could intercept and store every message, and then try deriving +the secret key from each pair of messages. + +This places implementors on the horns of a dilemma. On the one hand, +you want to store the ``K`` values to avoid reusing one; on the other +hand, storing them means they could fall into the hands of an adversary. +One can randomly generate ``K`` values of a suitable length such as +128 or 144 bits, and then trust that the random number generator +probably won't produce a duplicate anytime soon. This is an +implementation decision that depends on the desired level of security +and the expected usage lifetime of a private key. I can't choose and +enforce one policy for this, so I've added the ``K`` parameter to the +``encrypt`` and ``sign`` methods. You must choose ``K`` by +generating a string of random data; for ElGamal, when interpreted as a +big-endian number (with the most significant byte being the first byte +of the string), ``K`` must be relatively prime to ``self.p-1``; any +size will do, but brute force searches would probably start with small +primes, so it's probably good to choose fairly large numbers. It might be +simplest to generate a prime number of a suitable length using the +``Crypto.Util.number`` module. + + +Security Notes for Public-key Algorithms +================================================== + +Any of these algorithms can be trivially broken; for example, RSA can be +broken by factoring the modulus *n* into its two prime factors. +This is easily done by the following code:: + + for i in range(2, n): + if (n%i)==0: + print i, 'is a factor' + break + +However, ``n`` is usually a few hundred bits long, so this simple +program wouldn't find a solution before the universe comes to an end. +Smarter algorithms can factor numbers more quickly, but it's still +possible to choose keys so large that they can't be broken in a +reasonable amount of time. For ElGamal and DSA, discrete logarithms are +used instead of factoring, but the principle is the same. + +Safe key sizes depend on the current state of number theory and +computer technology. At the moment, one can roughly define three +levels of security: low-security commercial, high-security commercial, +and military-grade. For RSA, these three levels correspond roughly to +768, 1024, and 2048-bit keys. + +When exporting private keys you should always carefully ensure that the +chosen storage location cannot be accessed by adversaries. + +Crypto.Util: Odds and Ends +-------------------------------------------------- + +This chapter contains all the modules that don't fit into any of the +other chapters. + + +Crypto.Util.number +========================== + +This module contains various number-theoretic functions. + +**GCD(x,y)**: +Return the greatest common divisor of ``x`` and ``y``. + +**getPrime(N, randfunc)**: +Return an ``N``-bit random prime number, using random data obtained +from the function ``randfunc``. ``randfunc`` must take a single +integer argument, and return a string of random data of the +corresponding length; the ``get_bytes()`` method of a +``RandomPool`` object will serve the purpose nicely, as will the +``read()`` method of an opened file such as ``/dev/random``. + +**getStrongPrime(N, e=0, false_positive_prob=1e-6, randfunc=None)**: +Return a random strong ``N``-bit prime number. +In this context p is a strong prime if p-1 and p+1 have at +least one large prime factor. +``N`` should be a multiple of 128 and > 512. + +If ``e`` is provided the returned prime p-1 will be coprime to ``e`` +and thus suitable for RSA where e is the public exponent. + +The optional ``false_positive_prob`` is the statistical probability +that true is returned even though it is not (pseudo-prime). +It defaults to 1e-6 (less than 1:1000000). +Note that the real probability of a false-positive is far less. This is +just the mathematically provable limit. + +``randfunc`` should take a single int parameter and return that +many random bytes as a string. +If randfunc is omitted, then ``Random.new().read`` is used. + +**getRandomNBitInteger(N, randfunc)**: +Return an ``N``-bit random number, using random data obtained from the +function ``randfunc``. As usual, ``randfunc`` must take a single +integer argument and return a string of random data of the +corresponding length. + +**getRandomNBitInteger(N, randfunc)**: +Return an ``N``-bit random number, using random data obtained from the +function ``randfunc``. As usual, ``randfunc`` must take a single +integer argument and return a string of random data of the +corresponding length. + +**inverse(u, v)**: +Return the inverse of ``u`` modulo ``v``. + +**isPrime(N)**: +Returns true if the number ``N`` is prime, as determined by a +Rabin-Miller test. + + +Crypto.Random +================================================== + +For cryptographic purposes, ordinary random number generators are +frequently insufficient, because if some of their output is known, it +is frequently possible to derive the generator's future (or past) +output. Given the generator's state at some point in time, someone +could try to derive any keys generated using it. The solution is to +use strong encryption or hashing algorithms to generate successive +data; this makes breaking the generator as difficult as breaking the +algorithms used. + +Understanding the concept of **entropy** is important for using the +random number generator properly. In the sense we'll be using it, +entropy measures the amount of randomness; the usual unit is in bits. +So, a single random bit has an entropy of 1 bit; a random byte has an +entropy of 8 bits. Now consider a one-byte field in a database containing a +person's sex, represented as a single character ``'M'`` or ``'F'``. +What's the entropy of this field? Since there are only two possible +values, it's not 8 bits, but one; if you were trying to guess the value, +you wouldn't have to bother trying ``'Q'`` or ``'@'``. + +Now imagine running that single byte field through a hash function that +produces 128 bits of output. Is the entropy of the resulting hash value +128 bits? No, it's still just 1 bit. The entropy is a measure of how many +possible states of the data exist. For English +text, the entropy of a five-character string is not 40 bits; it's +somewhat less, because not all combinations would be seen. ``'Guido'`` +is a possible string, as is ``'In th'``; ``'zJwvb'`` is not. + +The relevance to random number generation? We want enough bits of +entropy to avoid making an attack on our generator possible. An +example: One computer system had a mechanism which generated nonsense +passwords for its users. This is a good idea, since it would prevent +people from choosing their own name or some other easily guessed string. +Unfortunately, the random number generator used only had 65536 states, +which meant only 65536 different passwords would ever be generated, and +it was easy to compute all the possible passwords and try them. The +entropy of the random passwords was far too low. By the same token, if +you generate an RSA key with only 32 bits of entropy available, there +are only about 4.2 billion keys you could have generated, and an +adversary could compute them all to find your private key. See +RFC 1750, +"Randomness Recommendations for Security", for an interesting discussion +of the issues related to random number generation. + +The ``Random`` module builds strong random number generators that look +like generic files a user can read data from. The internal state consists +of entropy accumulators based on the best randomness sources the underlying +operating is capable to provide. + +The ``Random`` module defines the following methods: + +**new()**: +Builds a file-like object that outputs cryptographically random bytes. + +**atfork()**: +This methods has to be called whenever os.fork() is invoked. Forking +undermines the security of any random generator based on the operating +system, as it duplicates all structures a program has. In order to +thwart possible attacks, this method shoud be called soon after forking, +and before any cryptographic operation. + +**get_random_bytes(num)**: +Returns a string containing ``num`` bytes of random data. + +Objects created by the ``Random`` module define the following variables and methods: + +**read(num)**: +Returns a string containing ``num`` bytes of random data. + +**close()**: +**flush()**: +Do nothing. Provided for consistency. + +Crypto.Util.RFC1751 +================================================== + +The keys for private-key algorithms should be arbitrary binary data. +Many systems err by asking the user to enter a password, and then +using the password as the key. This limits the space of possible +keys, as each key byte is constrained within the range of possible +ASCII characters, 32-127, instead of the whole 0-255 range possible +with ASCII. Unfortunately, it's difficult for humans to remember 16 +or 32 hex digits. + +One solution is to request a lengthy passphrase from the user, and +then run it through a hash function such as SHA or MD5. Another +solution is discussed in RFC 1751, "A Convention for Human-Readable +128-bit Keys", by Daniel L. McDonald. Binary keys are transformed +into a list of short English words that should be easier to remember. +For example, the hex key EB33F77EE73D4053 is transformed to "TIDE ITCH +SLOW REIN RULE MOT". + +**key_to_english(key)**: +Accepts a string of arbitrary data ``key``, and returns a string +containing uppercase English words separated by spaces. ``key``'s +length must be a multiple of 8. + +**english_to_key(string)**: +Accepts ``string`` containing English words, and returns a string of +binary data representing the key. Words must be separated by +whitespace, and can be any mixture of uppercase and lowercase +characters. 6 words are required for 8 bytes of key data, so +the number of words in ``string`` must be a multiple of 6. + + +Extending the Toolkit +-------------------------------------------------- + +Preserving a common interface for cryptographic routines is a good +idea. This chapter explains how to write new modules for the Toolkit. + +The basic process is as follows: + +1. Add a new ``.c`` file containing an implementation of the new +algorithm. +This file must define 3 or 4 standard functions, +a few constants, and a C ``struct`` encapsulating the state +variables required by the algorithm. + +2. Add the new algorithm to ``setup.py``. + +3.

The package is structured to make adding new modules easy. +This section is essentially complete, and the software interface will +almost certainly not change in an incompatible way in the future; all +that remains to be done is to fix any bugs that show up. If you +encounter a bug, please report it in the Launchpad bug tracker at + + https://launchpad.net/products/pycrypto/+bugs + +An example usage of the SHA256 module is: +>>> from Crypto.Hash import SHA256 +>>> hash = SHA256.new() +>>> hash.update('message') +>>> hash.digest() +'\xabS\n\x13\xe4Y\x14\x98+y\xf9\xb7\xe3\xfb\xa9\x94\xcf\xd1\xf3\xfb"\xf7\x1c\xea\x1a\xfb\xf0+F\x0cm\x1d' + +An example usage of an encryption algorithm (AES, in this case) is: + +>>> from Crypto.Cipher import AES +>>> obj = AES.new('This is a key456', AES.MODE_ECB) +>>> message = "The answer is no" +>>> ciphertext = obj.encrypt(message) +>>> ciphertext +'o\x1aq_{P+\xd0\x07\xce\x89\xd1=M\x989' +>>> obj2 = AES.new('This is a key456', AES.MODE_ECB) +>>> obj2.decrypt(ciphertext) +'The answer is no' + +One possible application of the modules is writing secure +administration tools. Another application is in writing daemons and +servers. Clients and servers can encrypt the data being exchanged and +mutually authenticate themselves; daemons can encrypt private data for +added security. Python also provides a pleasant framework for +prototyping and experimentation with cryptographic algorithms; thanks +to its arbitrary-length integers, public key algorithms are easily +implemented. + +As of PyCrypto 2.1.0, PyCrypto provides an easy-to-use random number +generator: + +>>> from Crypto import Random +>>> rndfile = Random.new() +>>> rndfile.read(16) +'\xf7.\x838{\x85\xa0\xd3>#}\xc6\xc2jJU' + +A stronger version of Python's standard "random" module is also +provided: + +>>> from Crypto.Random import random +>>> random.choice(['dogs', 'cats', 'bears']) +'bears' + +Caveat: For the random number generator to work correctly, you must +call Random.atfork() in both the parent and child processes after +using os.fork() + + +Installation +============ + +PyCrypto is written and tested using Python version 2.1 through 3.2. Python +1.5.2 is not supported. + +The modules are packaged using the Distutils, so you can simply run +"python setup.py build" to build the package, and "python setup.py +install" to install it. + +If the setup.py script crashes with a DistutilsPlatformError +complaining that the file /usr/lib/python2.2/config/Makefile doesn't +exist, this means that the files needed for compiling new Python +modules aren't installed on your system. Red Hat users often run into +this because they don't have the python2-devel RPM installed. The fix +is to simply install the requisite RPM. On Debian/Ubuntu, you need the +python-dev package. + +To verify that everything is in order, run "python setup.py test". It +will test all the cryptographic modules, skipping ones that aren't +available. If the test script reports an error on your machine, +please report the bug using the bug tracker (URL given above). If +possible, track down the bug and include a patch that fixes it, +provided that you are able to meet the eligibility requirements at +http://www.pycrypto.org/submission-requirements/. + +It is possible to test a single sub-package or a single module only, for instance +when you investigate why certain tests fail and don't want to run the whole +suite each time. Use "python setup.py test --module=name", where 'name' +is either a sub-package (Cipher, PublicKey, etc) or a module (Cipher.DES, +PublicKey.RSA, etc). +To further cut test coverage, pass also the option "--skip-slow-tests". + +To install the package under the site-packages directory of +your Python installation, run "python setup.py install". + +If you have any comments, corrections, or improvements for this +package, please report them to our mailing list, accessible via the +PyCrypto website: + + http://www.pycrypto.org/ + diff --git a/Cryptography/pycrypto-2.6.1/TODO b/Cryptography/pycrypto-2.6.1/TODO new file mode 100644 index 0000000..9116700 --- /dev/null +++ b/Cryptography/pycrypto-2.6.1/TODO @@ -0,0 +1,30 @@ +- Clean up and stabilize the Crypto.PublicKey API.

This allows numerous processes to + contribute to a system-wide seed. CryptoAPI stores + an intermediate random seed with every user.

This result is SHA-1 hashed, and + the output is used to seed an RC4 stream, which is + then used as the random stream and used to update + the stored seed. + +The only other detailed description I've found of the +sources of randomness for CryptGenRandom is this excerpt +from a posting +http://www.der-keiler.de/Newsgroups/comp.security.ssh/2002-06/0169.html + +From: Jon McClelland (dowot69@hotmail.com) +Date: 06/12/02 +... + +Windows, call a function such as CryptGenRandom, which has two of +the properties of a good random number generator, unpredictability and +even value distribution. This function, declared in Wincrypt.h, is +available on just about every Windows platform, including Windows 95 +with Internet Explorer 3.02 or later, Windows 98, Windows Me, Windows +CE v3, Windows NT 4, Windows 2000, and Windows XP. + +CryptGenRandom gets its randomness, also known as entropy, from many +sources in Windows 2000, including the following: +The current process ID (GetCurrentProcessID). +The current thread ID (GetCurrentThreadID). +The ticks since boot (GetTickCount). +The current time (GetLocalTime). +Various high-precision performance counters (QueryPerformanceCounter). +A Message Digest 4 (MD4) hash of the user's environment block, which +includes username, computer name, and search path. + +High-precision internal CPU counters, such as RDTSC, RDMSR, RDPMC (x86 +only-more information about these counters is at +developer.intel.com/software/idap/resources/technical_collateral/pentiumii/RDTSCPM1.HTM +). + +Low-level system information, such as idle time, kernel time, +interrupt times, commit limit, page read count, cache read count, +nonpaged pool allocations, alignment fixup count, operating system +lookaside information. + +Such information is added to a buffer, which is hashed using MD4 and +used as the key to modify a buffer, using RC4, provided by the user. +(Refer to the CryptGenRandom documentation in the Platform SDK for +more information about the user-provided buffer.) Hence, if the user +provides additional data in the buffer, this is used as an element in +the witches brew to generate the random data. The result is a +cryptographically random number generator. +Also, note that if you plan to sell your software to the United States +federal government, you'll need to use FIPS 140-1-approved algorithms. +The default versions of CryptGenRandom in Microsoft Windows CE v3, +Windows 95, Windows 98, Windows Me, Windows 2000, and Windows XP are +FIPS-approved. Obviously FIPS-140 compliance is necessary but not +sufficient to provide a properly secure source of random data. + +*/ +/* +[Update: 2007-11-13] +CryptGenRandom does not necessarily provide forward secrecy or reverse +secrecy.
