SILC (Secure Internet Live Conferencing) is a protocol which provides
secure conferencing services on the Internet over insecure channels.
SILC is similar to IRC, as they both provide conferencing services and
almost have the same commands. However, they differ internally: unlike
IRC, SILC is secure and has an entirely different network model
compared to IRC.
