irssi-plugin-otr binary package in Ubuntu Lunar ppc64el

 This plugin adds Off-The-Record (OTR) messaging support to the Irssi IRC
 client. Although primarily designed for use with the BitlBee IRC2IM
 gateway, it works within any query window, provided that your
 conversation partner's IRC client supports OTR.
 .
 OTR allows you to have private conversations over IM by providing:
  * Encryption - no one else can read your instant messages.
  * Authentication - you are assured the correspondent is who you think
    it is.
  * Deniability - the messages you send do _not_ have digital signatures
    that are checkable by a third party. Anyone can forge messages after
    a conversation to make them look like they came from you. However,
    _during_ a conversation, correspondents are assured the messages
    they see are authentic and unmodified.
  * Forward secrecy - if you lose control of your private keys,
    no previous conversation is compromised.
