Keybase proof

I hereby claim:

• I am RiANOl on github.
• I am rianol (https://keybase.io/rianol) on keybase.
• I have a public key whose fingerprint is 51C5 97E3 1F80 3F1F 53C5 A72C 0EC9 F1C1 A5C4 50D6

To claim this, I am signing this object:

require "digest"

def aes128_cbc_encrypt(key, data, iv)
  key = Digest::MD5.digest(key) if(key.kind_of?(String) && 16 != key.bytesize)
  iv = Digest::MD5.digest(iv) if(iv.kind_of?(String) && 16 != iv.bytesize)
  aes = OpenSSL::Cipher.new('AES-128-CBC')
  aes.encrypt
  aes.key = key
  aes.iv = iv
