Last revised Tue May 25 21:05:50 PDT 1993. What is YTalk? ============== YTalk is a multi-user drop-in replacement for the UNIX "talk" program. I have added encryption facilities to it, including private key and PGP authentication. Features ======== - Multi user capabilities. - Drop in replacement for /usr/ucb/talk. - Diffie-Hellman exponential key exchange for session keys. - IDEA encryption in CFB mode. - Password authentication. - PGP authentication. - Logging of conversations to a file. Known bugs and misfeatures ========================== - No security the first time you use it, until the random seed file is created (around 300 keystrokes). - Some problems with the talk daemons on Ultrix and SCO-Unix. - Port to Alpha (64bit) incomplete.
