rubyでの暗号化にrijndael aes128を使いたい。私はこのコードを持っています:

cipher = OpenSSL::Cipher::Cipher.new("aes-128-cbc")
cipher.encrypt
cipher.key = 'abcdef0123456789abcdef0123456789'
cipher.iv = '0000000000000000'
encrypted =   cipher.update('2~1~000024~0910~20130723092446~T~00002000~USD~F~375019001012120~0~0~00000000000~')
encrypted << cipher.final

これは機能していません。しかし、このPHP関数を使用すると:

<?php 
 function hex2bin($hex_string) 
  {
     return pack('H*', $hex_string);
  } 
 $data_to_encrypt = '2~1~000024~0910~20130723092446~T~00002000~USD~F~375019001012120~0~0~00000000000~';
  $key = 'abcdef0123456789abcdef0123456789'; 
  $iv = '0000000000000000'; 
  $key = hex2bin($key);
  $iv = hex2bin($iv); 
  $data_encrypted = bin2hex(mcrypt_encrypt(MCRYPT_RIJNDAEL_128, $key, $data_to_encrypt, MCRYPT_MODE_CBC, $iv));
  echo "Data encrypted: ".strtoupper($data_encrypted)."<br/>"; echo "Length: ".strlen($data_encrypted)."<br/>";
  ?>

目的の出力が得られました：

Ruby コードで同じ出力を生成するにはどうすればよいですか?

require 'openssl'

cleartext = '2~1~000024~0910~20130723092446~T~00002000~USD~F~375019001012120~0~0~00000000000~'

cipher = OpenSSL::Cipher::Cipher.new("aes-128-cbc")
cipher.encrypt
cipher.padding = 0
cipher.key = [key].pack('H*')
cipher.iv = [iv].pack('H*')
encrypted = cipher.update(cleartext)
encrypted << cipher.final
puts encrypted.unpack('H*').first.upcase
