- GnUPG support, I would like to add the ability sign or encrypt
messages. A user could paste their private key into a form that then saved it on the server in sql. There is probably a huge security issue with saving private keys on a server. I don't know of a php API, I would most likely use exec();
Please email me any comments, questions or concerns.
Squirrelmail, another webmail client has a gpg plugin which provides encryption and signing. Maybe this could be used as a starting point?
