PGPSigner project is a tool born out of the main virtues of a sysadmin: Lazyness and Impatience. Have you ever been to a PGP key signing party? It is fun, you verify all these ids, check the keys on the party list and then... then you get home. And find out that you have 47 different keys to sign...

Ajisai is a SSL/TLS implementation written entirely from scratch in C++. It uses Botan for performing the cryptography and X.509 handling. This is an alpha release, it is virtually certain that incompatible API changes will be made in the future. Suggestions on weak points in the API are most...
