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.

Note

The original algorithm implementation in Ruby by Max Prokopiev <max-prokopiev@yandex.ru>.

Aleksandar Simic then modified it to include a test suite and gem packaged it using gem-this. <asimic@gmail.com>

I switched the project to use rspec2.
