Re: [Cryptography] Size of the PGP userbase?

grarpamp:

some form of p2p message system where every address is a crypto key, masked for grandma by her contact list

You may have a look of "I2P Bote" it is severless, encrypted mail system, address is the public key, P2P based... nice tool. https://en.wikipedia.org/wiki/I2P#E-mail It is part of the Invisible Internet Project (I2P), a P2P darknet. The I2P router is router and client in one Java application. You have to install he I2P router first: http://www.i2p2.de Afterwards you can add the "I2P Bote plugin", the serverless mail system. SMTP- and POP3 support was on the ToDo list some times ago, I didn't have a look on the latest version of the project. Installation is not very easy, but possible. Best regards cane
