Ok, this poor fellow asks for a simple way to protect his private e-mail,
and what does he get?  A meta-discussion on legalities.  Well, here is
my suggestion for implementing the simple encryption in a UNIX environment:

The sender:

 % crypt < msg.txt > cypher               (use previously agreed-upon key)
 % uuencode cypher < cypher > cypher.uu
 % mail whoever@wherever -s crypted_message < cypher.uu

The recipient:

 % mail                      (receive mail, save in appropriate file)
 % uudecode cypher.uu
 % crypt < cypher > msg.txt    (must have same key as sender)
 % more msg.txt
 
Simple enough?  Of course, you'll have to communicate the crypt key by
some other means in advance.
