=head1 DESCRIPTION

Creates an encrypted cookie-like string with a MAC (checksum) 
from a hash of critical and non-critical values. The MAC is 
created on only the critical values. Decryption will fail if
the string has been altered and the MAC does not match when 
the string is decrypted.

Particularly useful when using COOKIES and will do all the 
hard work for Apache::AuthCookie
