+.SH DESCRIPTION
+Off-the-Record (OTR) Messaging 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 \fInot\fP 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,
+ \fIduring\fP 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.
+.PP
+The OTR Toolkit is useful for analyzing and/or
+forging OTR messages. Why do we offer this? Primarily, to make
+absolutely sure that transcripts of OTR conversations are really easy
+to forge after the fact. [Note that \fIduring\fP an OTR conversation,
+messages can't be forged without real-time access to the secret keys on
+the participants' computers, and in that case, all security has already
+been lost.] Easily-forgeable transcripts help us provide the
+"Deniability" property: if someone claims you said something over OTR,
+they'll have no proof, as anyone at all can modify a transcript to make
+it say whatever they like, and still have all the verification come out
+correctly.
+
+Here are the six programs in the toolkit:
+
+ - otr_parse
+ - Parse OTR messages given on stdin, showing the values of all the
+ fields in OTR protocol messages.
+
+ - otr_sesskeys our_privkey their_pubkey
+ - Shows our public key, the session id, two AES and two MAC keys
+ derived from the given Diffie-Hellman keys (one private, one public).
+
+ - otr_mackey aes_enc_key
+ - Shows the MAC key derived from the given AES key.
+
+ - otr_readforge aes_enc_key [newmsg]
+ - Decrypts an OTR Data message using the given AES key, and displays
+ the message.
+ - If newmsg is given, replace the message with that one, encrypt
+ and MAC it properly, and output the resulting OTR Data Message.
+ This works even if the given key was not correct for the original
+ message, so as to enable complete forgeries.
+
+ - otr_modify mackey old_text new_text offset
+ - Even if you can't read the data because you don't know either
+ the AES key or the Diffie-Hellman private key, but you can make a
+ good guess that the substring "old_text" appears at the given
+ offset in the message, replace the old_text with the new_text
+ (which must be of the same length), recalculate the MAC with the
+ given mackey, and output the resulting Data message.
+ - Note that, even if you don't know any text in an existing message,
+ you can still forge messages of your choice using the
+ otr_readforge command, above.
+
+ - otr_remac mackey flags snd_keyid rcv_keyid pubkey counter encdata revealed_mackeys
+ - Make a new OTR Data Message, with the given pieces (note that the
+ data part is already encrypted). MAC it with the given mackey.
