(description

"OTR 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.")
