What is that ?

This is a library intended to be used as a layer on top of TLS implementations to make message passing secure.
It might be useful to develop client server applications and distributed systems required to use message passing, but in a modern world that's better to do it secure.
Generally, this library provide a mechanism to allow make a calls to the remote host in a secure manner, and also provide a good way to authentificate users and limit access to the calls.

Features

Since 0.5.xx development protocol will be changed to SXT (Secure eXtended Transport).

Remote procedure calls

• Simple and clean S-expression based
• Return code and S-expression replies
• Possibility to create a special groups of RPC
