tea(1) - Linux man page

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
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.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 CGIs to feed to the browser. Triple encryption will be offered later.
