我的加密功能正常工作但是我无法弄清楚如何获得解密功能以提供正确的输出.

这是我的加密功能:

function Encrypt($data, $secret)
{    
  //Generate a key from a hash
  $key = md5(utf8_encode($secret), true);

  //Take first 8 bytes of $key and append them to the end of $key.
  $key .= substr($key, 0, 8);

  //Pad for PKCS7
  $blockSize = mcrypt_get_block_size('tripledes', 'ecb');
  $len = strlen($data);
  $pad = $blockSize - ($len % $blockSize);
  $data .= str_repeat(chr($pad), $pad);

  //Encrypt data
  $encData = mcrypt_encrypt('tripledes', $key, $data, 'ecb');

  return base64_encode($encData);

}

这是我的解密功能:

function Decrypt($data, $secret)
{
    $text = base64_decode($data);

    $data = mcrypt_decrypt('tripledes', $secret, $text, …
