mcrypt_crypt和decrypt的结果不匹配

Question

我有两种加密和解密方法，但是输入值与解密函数的输出值不匹配，请你帮我找到问题？

private function encryptMd($md)
{
    $md = serialize($md);
    //encryption should happen here
    $md = mcrypt_encrypt(MCRYPT_RIJNDAEL_256, $this->secret, $md, MCRYPT_MODE_ECB);
    $md = gzcompress($md);
    $md = base64_encode($md);
    return $md;
}

private function decryptMd($md)
{
    $md = base64_decode($md);
    $md = gzuncompress($md);
    // decryption happen here
    $md = trim(mcrypt_decrypt(MCRYPT_RIJNDAEL_256, $this->secret, $md, MCRYPT_MODE_ECB));
    $md = unserialize($md);
    return $md;
}

结果如下：

第一个字符串： 订单ID = 1111264＆安培; cardnumber = 4012001037141112＆安培; cardname =测试＆安培; cardtype = VISA＆安培;金额= 100安培; EXPDATE = 0214

加密字符串： eJwBgAB // 4LFthFrKDuzX7v + 90h2j24xrEnKHHxefzvh5si5yKxEJxtOAo8XG923Ako0eYP7JVH03yN9LPdb / V8JghJVi8tPvloqlEOFwDHUbwBoFGHBNvTRq0vgMRN / Wlpfk8e + UYQWV4TRYYNWNWxVLiwMFWWOk6bsESDgRBkMDQcp // OOFkg5cg ==

收到的字符串： eJwBgAB // 4LFthFrKDuzX7v + 90h2j24xrEnKHHxefzvh5si5yKxEJxtOAo8XG923Ako0eYP7JVH03yN9LPdb / V8JghJVi8tPvloqlEOFwDHUbwBoFGHBNvTRq0vgMRN / Wlpfk8e + UYQWV4TRYYNWNWxVLiwMFWWOk6bsESDgRBkMDQcp // OOFkg5cg ==

解密结果： FALSE

问题在于$ this-＆gt;秘密在解密时是空的。无论如何，谢谢。
