This is a (bash) shell script that can be used as an external program with the client's external encryption program support. Both the sender and receiver must be encrypting with each other using this script as the external cipher program.

This script ciphers the messages you send and receive between each other, doing ascii-armoring, which makes the data safe to send over irc.

The utility of this script has been somewhat obviated because the client now features built in strong cryptography. However, the facility to use an external script (modeled after this script) is still present and could be used for specific botique encryption needs.

This script first appeared in epic4-1.1.3.
