02 [1] determine what's missing in OpenPGP-SDK
03 [1] make a separate layer in RS to handle PGP. AuthPGP is too close to libretroshare.
03 [3] make a separate layer in RS to handle PGP. AuthPGP is too close to libretroshare.
04 [1] write the new AuthGPG class
05 [ ] consider removing thread behaviour of AuthGPG
06 [ ] remove callback system and services from AuthGPG, since it's not useful anymore
07 [ ] make all RS use GPGIdType isntead of std::string.
