NAME

Algorithm::IRCSRP2 - IRC channel encryption algorithm

VERSION

version 0.501

DESCRIPTION

Algorithm::IRCSRP2 implements the IRCSRP version 2 algorithm as specified in http://www.bjrn.se/ircsrp/ircsrp.2.0.txt.

From the specification:

IRCSRP is based on the SRP-6 protocol [3] for password-authenticated key
agreement. While SRP was originally designed for establishing a secure,
authenticated channel between a user and a host, it can be adapted for group
communcations, as described in this document.

See https://gitorious.org/ircsrp/ircsrp for a working version used in Pidgin.
