Ruby on Rails Decryption

Question

The following function works perfect in PHP. How can it be translated in Ruby on Rails.

Please note that both privateKey and iv are 32 characters long.

m         


        

Answer 1

Here some code which works for me :

def decrypt_data(data, pwd, iv)
    encrypted_data = Base64.decode64(data)
    aes = OpenSSL::Cipher::Cipher.new("AES-256-CBC")
    aes.decrypt
    aes.key = Digest::MD5.hexdigest(pwd)
    aes.iv = iv
    result = aes.update(encrypted_data) + aes.final 
end

In my example the password is encrypted with MD5.

I hope this help

Answer 2

You are base64 decoding it in the php example. Are you doing that in the ruby one as well?

require "base64"
Base64.decode64(encrypted)

Other than that, the code looks right to me.
