cpg_overview

The CPG library is delivered with the openais project. This library is used to create distributed applications that operate properly during partitions, merges, and faults.

The library provides a mechanism to: * handle abstraction for multiple instances of an CPG library in one application * join one or more groups * leave one or more groups * Deliver messages to members of that group * Deliver configuration changes

The CPG library encrypts all messages sent over the network using the SOBER-128 stream cipher. The EVS library uses HMAC and SHA1 to authenticate all messages. The CPG library uses SOBER-128 as a pseudo random number generator. TheCPG library feeds the PRNG using the /dev/random Linux device.

This software is not yet production, so there may still be some bugs.
