OTR allows you to have private conversations over IM 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, correspondents are assured the messages they see are authentic and unmodified.
  • Forward secrecy - if you lose control of your private keys, no previous conversation is compromised.
