You set an encryption key with the SetKey <nick/#chan> <key> command. From then on, all messages to that target will be encrypted. Received messages are automatically decrypted. See the help command for more info.
Please have a look at "Security considerations" of the Fish-Module before using it as they also apply to this module.
