Is there any difference between Ruby 'AES-128-CBC' a

Ruby代码是

require 'base64'
require 'openssl'
def ruby_dec iv, key, encrypted
  decipher = OpenSSL::Cipher::AES.new(128, :CBC)
  #decipher.padding = 0 
  decipher.decrypt
  decipher.key = key
  decipher.iv = iv
  ciphertext = Base64.decode64 encrypted
  decipher.update(ciphertext) + decipher.final
end

def ruby_enc iv, key, plaintext 
  enc = OpenSSL::Cipher.new 'aes-128-cbc'
  enc.encrypt
  enc.key = key
  enc.iv = iv
  Base64.encode64(enc.update(plaintext) + enc.final)
end
iv = Base64.decode64("TOB+9YNdXSbkSYIU7D/IpQ==")
key =  Base64.decode64("7DxoShENB0D+8xrwOwSbi1TPQBiIaFq2yveoUkutCpM=")
plaintext = "testtesttest"
encrypted = ruby_enc iv, key, plaintext
puts "encrypted is #{encrypted}"
ruby_dec iv, key, encrypted
puts "plaintext is #{plaintext}"

然后

$ ruby enc_dec.rb #the above code
encrypted is LXJmnM7t+HGKi2iI51ethA==
plaintext is testtesttest

现在PHP代码是

function php_dec($iv, $key, $encrypted) { 
  $cipher_algorithm    = 'rijndael-128';
  $cipher_mode = 'cbc';
  $key = base64_decode($key);
  $iv = base64_decode($iv);
  $ciphertext = base64_decode($enctypted);
  return $ciphertext;
}

function php_enc($iv, $key, $plaintext){
  $td = mcrypt_module_open(MCRYPT_RIJNDAEL_128, '', MCRYPT_MODE_CBC, '');
  $mcrypt_key = base64_decode($key);
  $iv = base64_decode($iv);
  mcrypt_generic_init($td, $mcrypt_key, $iv);
  $ciphertext = mcrypt_generic($td, $plaintext);
  retun base64_encode($ciphertext); 
}
$iv = base64_decode("TOB+9YNdXSbkSYIU7D/IpQ==");
$key =  base64_decode("7DxoShENB0D+8xrwOwSbi1TPQBiIaFq2yveoUkutCpM=");
$plaintext = "testtesttest";
$encrypted = php_enc($iv, $key, $plaintext);
echo "encrypted is ".$encrypted."'n";
php_dec($iv, $key, $encrypted);
echo "plaintext is ".$plaintext."'n";
$ruby_encrypted = base64_encode("LXJmnM7t+HGKi2iI51ethA==");
php_dec($iv, $key, $ruby_encrypted);
echo "plaintext is ".$plaintext."'n";

然后我得到

$ php enc_dec.php
encrypted is SUR33tXu32JjR9JAKIGL7w==
plaintext is testtesttest
plaintext is testtesttest

密文与ruby不同。现在我尝试用PHP制作的密文来解密ruby。

$ pry
  [1] pry(main)> load 'enc_dec.rb'
  [2] pry(main)> iv = Base64.decode64("TOB+9YNdXSbkSYIU7D/IpQ==")    
  => "L'xE0~'xF5'x83]]&'xE4I'x82'x14'xEC?'xC8'xA5"
  [3] pry(main)> key =  Base64.decode64("7DxoShENB0D+8xrwOwSbi1TPQBiIaFq2yveoUkutCpM=")    
  => "'xEC<hJ'x11'r'a@'xFE'xF3'x1A'xF0;'x04'x9B'x8BT'xCF@'x18'x88hZ'xB6'xCA'xF7'xA8RK'xAD'n'x93"
  [4] pry(main)> ruby_dec iv, key, Base64.decode64("SUR33tXu32JjR9JAKIGL7w==")
  OpenSSL::Cipher::CipherError: data not multiple of block length
  from enc_dec.rb:12:in `final'
  [5] pry(main)> 

Ruby"AES-128-CBC"和PHP"rijndael-128"加密之间有什么区别吗？我如何用ruby解密？
