but it can be used by any other program that knows how to use checkpassword
compatible authentication.

Encryption plugin for Pidgin instant messaging client.
Off-the-Record (OTR) Messaging allows you to have private
conversations over instant messaging 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, 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.
