OTR (Off-The-Record) Messaging

Official Docs: https://otr.cypherpunks.ca/
Wikipedia: https://en.wikipedia.org/wiki/Off-the-Record_Messaging

OTR is a plugin for IRC clients that provides client to client encryption between two users during private messaging.

OTR ensures privacy and security by providing the following features:

Encryption:
    No one else can read your instant messages.

Authentication:
    You are provided differents forms of authentication to be 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, your correspondent is assured the messages he sees are authentic and unmodified.

Perfect forward secrecy:
    If you lose control of your private keys, no previous conversation is compromised.

This guide will be going over setting up OTR for clients that are not pidgin. For Pidgin OTR, see Official Docs.

By default, your packagae manager should have otr pre-packaged for your OS, especially if it is Debian or Ubuntu.
Simply type "apt-cache search hexchat-otr" if on debian or ubuntu. If using a different distro, use the package manager for that distro.

However, some versions of Debian/Ubuntu do not have have otr support for some reason. You can compile this code here if this is the case.
