Theory

Algorithms

Symmetric encryption

  • 3DES - or Triple Data Encryption Algorithm (TDEA or Triple DEA) symmetric-key block cipher, which applies the Data Encryption Standard (DES) cipher algorithm three times to each data block.
  • AES - is a symmetric-key block cipher algorithm and U.S. government standard for secure and classified data encryption and decryption (also known as Rijndael).
  • Blowfish - is a symmetric-key block cipher, designed in 1993 by Bruce Schneier. Notable features of the design include key-dependent S-boxes and a highly complex key schedule.

Hash functions

  • MD5 - is a widely used hash function producing a 128-bit hash value. MD5 was initially designed to be used as a cryptographic hash function, but it has been found to suffer from extensive vulnerabilities. It can still be used as a checksum to verify data integrity, but only against unintentional corruption.
  • SHA1 - is a cryptographic hash function designed by the NSA. SHA-1 produces a 160-bit hash value known as a message digest. SHA-1 is no longer considered secure against well-funded opponents.
  • SHA2 - is a set of hash functions designed by the NSA. SHA-256 and SHA-512 are novel hash functions computed with 32-bit and 64-bit words, respectively. They use different shift amounts and additive constants, but their structures are otherwise virtually identical, differing only in the number of rounds.
