... and encrypted messaging system

This system allows you to generate certificates, revoke them if need be and to download certificates of other users. Furthermore, we offer an encrypted messaging service for which you need to register in order to send out messages. We also offer state-of-the-art challenge/response-based login in addition to a password-based login. In case keys get compromised, you can easily flag them as br0ken. This interface has been written in Haskell.

Haskell is faster than C++, more concise than Perl, more regular than Python, more flexible than Ruby, more typeful than C#, more robust than Java, and has absolutely nothing in common with PHP. Audrey Tang
