Question

If I write the following code

mcrypt_encrypt(MCRYPT_RIJNDAEL_128, $key, $raw, MCRYPT_MODE_CBC, $iv);

How to write in ruby?

Answer 1

Here is Ruby equivalent using OpenSSL,

  cipher = OpenSSL::Cipher::Cipher.new("aes-128-cbc")
  cipher.encrypt
  cipher.key = key
  cipher.iv = iv
  encrypted = cipher.update(raw)
  encrypted << cipher.final
