# $EPIC: encrypt,v 1.3 2000/09/18 22:23:39 jnelson Exp $
Synopsis:
   encrypt [<nickname|channel> [<key>]]

Description:
   This allows you to maintain an encrypted conversation with a person
   or channel.  Any messages you send to the specified target will
   automatically be encrypted.  If the recipient has likewise specified
   the proper encryption key for you, the incoming message will
   automatically be decrypted.  Both parties must use the same key for
   the messages to be decrypted.  Anyone receiving an encrypted message
   without specifying the proper key will instead see "[ENCRYPTED
   MESSAGE]" on their screen.

   If no arguments are specified, a list of nicknames (or channels)
   that encrypted messages are being sent to is shown, along with their
   respective keys.  If only a nickname or channel is given, the
   encrypted session with that target is ended.

Examples:
   To start an encrypted session with JoeBob using the key "foobar":
      /encrypt joebob foobar

   To start an encrypted session with channel #blah using key "booya":
      /encrypt #blah booya

   To list your current encrypted sessions:
      /encrypt

   To end your encrypted session with JoeBob:
      /encrypt joebob

Other Notes:
   IrcII's built-in encryption is fine for most purposes, but since the
   raw algorithm is hardcoded into the client, it's not terribly secure.
   It is generally suitable to deter prying eyes, but is certainly not
   suitable for genuinely sensitive transactions.

   Encrypted messages may be sent across DCC CHAT connections.  However,
   non-EPIC3 clients will probably be confused by them.
