Trillian

    From Consumerium development wiki R&D Wiki

    Trillian chat code provides 128-bit encryption (SecureIM) over the ICQ chat net. This capability may eventually be in Jabber or other free software, and might even be integrated into Wiki code.

    For now, if you want to chat securely, Trillian is the only thing you can use.
