Description:

This module implements TEA, the Tiny Encryption Algorithm, and some
Modes of Use based on CBC, compatibly in both Perl and JavaScript.
This enables CGI scripts to communicate with browsers. The
functionality of this Tea.pm is quite different from Abhijit
Menon-Sen's TEA.pm; the encryption is done in pure Perl, all
cyphertext is ascii-encoded, and notably there is a subroutine to
return JavaScript code which implements compatible functions in
JavaScript. Tea.pm was written to give an encryption engine which
could be dropped into both ends of an HTTP connection, in Perl at the
CGI end and in JavaScript at the browser end.
