NAME

tea - Perl script to give command-line access to Crypt::Tea_JS.pm

SYNOPSIS

tea -c filename   # enCrypts filename
tea filename      # decrypts filename
tea -s filename   # calculates ascii digital Signature for filename
tea -j            # outputs Javascript code to do compatible encryption
tea -o            # set Old mode, for Crypt::Tea-compatibility
tea -h            # prints this Helpful message
ps axww | tea -s  # have the best password in town !

For encryption and decryption, you will be asked for a password. It should be a sufficiently longish string; say 17 random 8-bit bytes.

DESCRIPTION

This script uses the Crypt::Tea_JS.pm module to offer new TEA, the Tiny Encryption Algorithm, and some Modes of Use based on CBC, 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 JS, and this can be used by CGIs to feed to the browser.
