this is a mirror of the vanished crypt19 gem

crypt

Description

The Crypt library is a pure-ruby implementation of a number of popular encryption algorithms. Block cyphers currently include Blowfish, GOST, IDEA, Rijndael (AES), and RC6. Cypher Block Chaining (CBC) has been implemented.

Crypt is written entirely in ruby so deployment is simple - no platform concerns, no library dependencies, nothing to compile.

This version is tested on Ruby 1.8.7 and 1.9.1.

Usage

TODO See http://crypt.rubyforge.org/ for now.

Installation

gem install crypt19
