User-level changes: ================== - libgpgme is not used anymore; it is replaced by a built-in piece of code called OpenPGP-SDK (http://openpgp.nominet.org.uk/cgi-bin/trac.cgi) that was improved to be used by RetroShare for handling PGP keys. - the gnupg keyring is not used anymore. Now, RetroShare has it's own gpg keyring, shared by all instances. On linux it's located in ~/.retroshare/pgp/. A lock system prevents multiple locations to read/write keyrings simultaneously. - the trust database from gnupg is not documented, so RetroShare cannot import it. This comes from the fact that the GPG standard (RFC4880) asks explicitly not to export trust information. So RetroShare has it's own trust DB shared by locations. This means you need to re-trust people. Sorry for that! - at start, if no keyring is found, RS will propose to copy the gnupg keyring to use your existing keys. Clicking on "OK" will do the copy, and you should find back all existing locations, except for DSA keys. - locations for which the suitable keypair is not in the keyring will not be displayed in the login window - locations for which the suitable keypair is not a RSA/RSA key will not be displayed. RetroShare does not support DSA/Elgamal keypairs yet. - a key import/export exchange function has been added in the certificate creation window (you go there from the login window by clicking on "manage keys/locations". This allows to easily create a new location with the same pgp key on another computer. To obtain a suitable keypair using gnupg, you need to concatenate the encrypted private key and the public key into an ascii file. This can be done using: gpg -a --export-secret-keys [your ID] > mykey.asc gpg -a --export [your ID] >> mykey.asc - importing a key with subkeys in not yet possible. Please remove subkeys before importing. - The code has been tested for a reasonnable amount of time, but it's not possible to prevent some new bugs to appear. Please report them asap supplying: call-stacks if possible, and terminal output. In particular, openpgp has some assert()'s that should not be triggered unless RetroShare is calling it in an improper way. Internal changes ================ - a specific component, PGPHandler, takes care of the interface between openpgp-sdk and RetroShare openpgp-sdk is c-code, with it's own memory management, which has been kept well separated from RetroShare. - GPG Ids are now a specific class (not a std::string anymore) for code consistency reasons. As strings are still used in many places, this requires a few conversions. In particular, AuthGPG takes strings as function params and calls GPGHandler with the proper PGPIdType class. In the future, RetroShare should only use PGPIdType. The same will be done for SSL ids. - signature cleaning is still handled by the Retroshare built-in function, not by openpgp, but we will do this later. Still to do =========== - DSA needs subkey handling, since the encryption is performed by a Elgamal subkey. Not sure this will be done. - GPGIds/SSLIds cleaning (meaning replace strings by appropriate types). Lots of confusion throughout the code in retroshare-gui in particular. - key removal from keyring. This is a challenge to keep locations synchronised. git-svn-id: http://svn.code.sf.net/p/retroshare/code/trunk@5293 b45a01b8-16f6-495d-af2f-9b41ad6348cc |
