RC4

RC4 is a pure Ruby implementation of the Rc4 algorithm.

Usage

First require the gem:

require ‘rc4’

To encrypt:

key = “nuff rspec”
enc = RC4.new(key)
encrypted = enc.encrypt(“super-cool-test”)

To decrypt:

dec = RC4.new(key)
decrypted = dec.decrypt(encrypted)

Since encrypt method is used for encryption and decryption, decrypt is
just an alias to encrypt in order to make the usage more intuitive.

Aleksandar Simic then modified it to include a test suite and gem
packaged it using gem-this.

I switched the project to use rspec2 and am the now the project’s primary maintainer.
