NAME

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

SYNOPSIS

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.

DESCRIPTION

This script uses the Crypt::Tea.pm module to offer 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 GCIs to feed to the browser. Triple encryption will be offered later.
