Off-the-Record Messaging
Tuesday, May 8th, 2007
- 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.
