Jabber with Off the Record (OTR) Encryption Background

More and more, governments and corporations attempt to read your personnel network communications. From the illegal wiretaps by National Security Agency (NSA) to Sweden’s new law requiring all network traffic originating to or from Sweden be archived, no one is safe. A recent study even showed one out of every three system administrators viewed resources, including your private data, to which they were not allowed access. Being these individuals have access to the network path, network based encryption can not be the only answer (think MitM attacks). Fortunately, Off-the-Record (OTR) messaging provides a solution around this issue.

What is jabber?

Jabber is an open standard for instant messages as well as voice and video chat. With jabber, you can send and receive messages between corporate services like Google Chat, as well as activist providers like riseup.net or autistici.org.

OTR provides four major points to help ensure private conversations: encryption, authentication, deniability and perfect forward secrecy. This page discusses these points in greater detail.
