Nick asked on ruby-talk how to do simple encryption using ruby and it’s built in OpenSSL module.

I’ve just registred an ezcrypto module at rubyforge, which should make it a lot easier to use. There currently is no code there, but I will be uploading something shortly.

However to get started here is a little starter:

require 'openssl'
require 'digest/sha2'
cipher = OpenSSL::Cipher::Cipher.new('aes-192-cbc')  
cipher.encrypt
cipher.key=Digest::SHA256.digest("super secret password")
encrypted= cipher<<"data to be encrypted..." # Note this needs to be padded to be the block size of the cipher.

To do decrypt just use cipher.decrypt instead.
