ircII help - encrypt

Usage: ENCRYPT [-<type>] [| []]

       ENCRYPT [-showkeys]   encrypt allows you to hold an encrypted conversations with   a person or a whole channel. Once a nickname/channel and   key is specified, all messages you send to that   nickname/channel will automatically be encrypted using the   given key. Likewise, any messages from that nickname/channel   will automatically be decrypted. ircII is smart enough to know   if the incoming message isn't encrypted and will not attempt to   decrypt it. If you received an encrypted message from someone   for whom you haven't specified a key, it will be displayed as   [ENCRYPTED MESSAGE].

  The <key> can be any text which is to be used an they key   for encryption/decryption of the conversation. It is up to   you and the people you wish to talk to about how to agree upon   a key and how to communicate it to one another.

  If <type> is specified, ircII will use this cryptography   method rather than the default. The current option is   only -cast. AES will be supported soon.

  For example, if user CheeseDog wishes to talk encryptedly with   user DogCheese, they must first agree on an encryption key   (case sensitive), say foo. Then user CheeseDog must issue a     encrypt DogCheese foo   and user DogCheese must issue a     encrypt CheeseDog foo   Thereafter, all messages sent between CheeseDog and DogCheese   will be encrypted and decrypted automatically.

  If encrypt is given with a nickname but no key, then encrypted   conversation is ended with that user.

  If encrypt is given with no arguments, the list of encrypted   users and encryption types are displayed. If the -showkeys   option is specified, the keys for each user are also displayed.

  older ircII used a built in encryption method that isn't terribly   secure. After ircII 4.4, CAST-128 support was added and is now   the default. You can use another if you so choose, see   set/encrypt_program for information about this. Note that   in releases prior to 4.4B, ircII used a different type of program   API for ENCRYPT_PROGRAM.

  If you are sending encrypted messages to a user or channel, you   can toggle it off and on in a message line by inserting the   control-E character in the input line. This is usually done   by hitting control-Q then control-E. An inverse video E will   appear in the input line.

Note:   Control-q is bound (see bind) to quote_character by default.   It is frequently necessary to change this to some other char.
