     These commands implement a secure communication channel; it
     is like _\bm_\ba_\bi_\bl(1), but no one can read the messages except the
     intended recipient.  The method embodies a public-key cryp-
     tosystem using knapsacks.

     To receive messages, use _\be_\bn_\br_\bo_\bl_\bl; it asks you for a password
     that you must subsequently quote in order to receive secret
     mail.

     To receive secret mail, use _\bx_\bg_\be_\bt.	It asks for your pass-
     word, then gives you the messages.

     To send secret mail, use _\bx_\bs_\be_\bn_\bd in the same manner as the
     ordinary mail command.  (However, it will accept only one
     target).  A message announcing the receipt of secret mail is
     also sent by ordinary mail.

     It should be integrated with ordinary mail.  The announce-
     ment of secret mail makes traffic analysis possible.
