It looks like the gpg+firefox+windows+gmail puzzle is solved
This is a quick post but I don’t want to forget this! The guys over at voipsec.eu mention these 2 useful links:
“FireGPG is a Firefox extension under MPL which brings an interface to encrypt, decrypt, sign or verify the signature of text in any web page using GnuPG.”
“Gpg4win is a installer package for Windows (2000/XP/2003/Vista) with computer programs and handbooks for EMail and file encryption. Both relevant cryptography standards are supported, OpenPGP and S/MIME (the latter is in progress and currently works with GnuPG2 and Claws Mail).”
I’ll try these out sometime soon.
