If there is a blowfish key set for a IRC channel this plugin will always encrypt and decrypt IRC messages of that channel. After the plugin has registered it will push itself to the first position in the plugin pipeline. This is necessary that all other plugins will get the decrypted IRC messages. This plugin is compatible to blowfish irssi plugin: CONSTRUCTOR new Creates a new plugin object. Takes a hash to set blowfish keys for channels: '#perl' => 'secret', '#poe' => 'foo', It's possible to change this later using "INPUT EVENTS". INPUT EVENTS The plugin registers the following state handler within your session: set_blowfish_key Parameters: $channel $blowfish_key Set blowfish key for a channel. If there was a key set already it will be overwritten. del_blowfish_key Remove blowfish key from a channel. Parameters: $channel AUTHOR Johannes 'plu' Plunien SEE ALSO POE::Component::IRC Crypt::Blowfish_PP
