tea \- Perl script to give command\-line access to Crypt::Tea.pm
\& tea -c filename # encrypts filename
\& tea filename # decrypts filename
\& tea -s filename # calculates ascii digital signature for filename
\& tea -j # outputs JavaScript doing compatible encryption
\& tea -h # prints this message
For encryption and decryption, you will be asked for a password.
It should be a sufficiently longish string; say 17 random 8\-bit bytes.
This script uses the Crypt::Tea.pm module to offer \s-1TEA\s0, the Tiny
Encryption Algorithm, and some Modes of Use based on \s-1CBC\s0, compatibly in
both Perl and JavaScript.
The various options offer encryption, decryption and digest, and all
cyphertext is ascii-encoded to prevent munging. Another option returns
JavaScript code which offers identical functions in \s-1JS\s0, and this can
be used by GCIs to feed to the browser. Triple encryption will be
