DESCRIPTION

These commands implement a secure communication channel; it is like mail, but
no one can read the messages except the intended recipient.  The method
embodies a public-key cryptosystem using knapsacks.

To receive messages, use the enroll command; it asks you for a password that
you must subsequently quote in order to receive secret mail.

To receive secret mail, use xget.  It asks for your password, then gives you
the messages.

To send secret mail, use xsend in the same manner as the ordinary mail command.
(However, it accepts only one target.)  A message announcing the receipt of
secret mail is also sent by ordinary mail.

Note:  Secret mail should be integrated with ordinary mail.  The announcement
       of secret mail makes traffic analysis possible.
