providing: (1) Encryption: No one else can read your instant messages.  (2)
Authentication: You are assured the correspondent is who you think it is.  (3)
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.  (4) Perfect forward secrecy: If you lose control of your private
keys, no previous conversation is compromised.")

    (description
     "Pidgin-OTR is a plugin that adds support for OTR to the Pidgin instant
messaging client.  OTR (Off-the-Record) Messaging allows you to have private
conversations over instant messaging by providing: (1) Encryption: No one else
can read your instant messages.  (2) Authentication: You are assured the
correspondent is who you think it is.  (3) 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.  (4) Perfect forward secrecy:
If you lose control of your private keys, no previous conversation is
compromised.")
