Off-the-Record Messaging library
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, your correspondent is assured the messages they see are authentic and unmodified. - Perfect forward secrecy - If you lose control of your private keys, no previous conversation is compromised. . This package provides the OTR library.
