Written by Alex Boussinet   

Modified by Mark Percival 

This ruby gem is simply a modification of Alex Boussinet's Ruby-AES(normal implemenation)

which can be found at 

I've fixed 2 issues to make it compatible with OpenSSL:

- Correctly padding the blocks

- Generating a key and IV from a password and random salt

# 

    require 'rubygems'

    require 'ruby-aes'

    require 'base64'

    enc = Aes.openssl_encrypt("pass", "test", :salt => "1831BD4EC8E35CC8", :size => 256, :mode => 'CBC')

    p Base64.b64encode(enc[:salted])

    dec = Aes.openssl_decrypt("pass", enc[:salted])

    p dec

Valid modes are:

- ECB (Electronic Code Book)

- CBC (Cipher Block Chaining)

- OFB (Output Feedback)

- CFB (Cipher Feedback)

Valid key length:

- 128 bits

- 192 bits

- 256 bits

For a really good encryption, 256 bits CBC is recommanded.
