OpenPGP key exchange for humans
monkeysign is a tool to overhaul the OpenPGP keysigning experience and bring it closer to something that most primates can understand.
The project makes use of cheap digital cameras and the type of bar code known as a QRcode to provide a human-friendly yet still-secure keysigning experience.
No more reciting tedious strings of hexadecimal characters. And, you can build a little rogue’s gallery of the people that you have met and exchanged keys with!
