MCrypt rijndael-256到OpenSSL AES-256-ECB转换

问题描述

由于不推荐使用Mcrypt，因此我想在代码中使用OpenSSL，因为我们已经在服务器中使用php 7.2.4.

Since Mcrypt is deprecated, I want to use OpenSSL instead in my code since we already using php 7.2.4 in our server.

我已使用以下代码进行加密/解密.

I have used following code for Encryption/Decryption.

//加密

function encrypt($text, $salt='') {
        if ($text == "") return "";
        if ($salt == "") $salt = 'DiAo74dOO09T48YESmuvbS0T';
        return trim(base64_encode(mcrypt_encrypt(MCRYPT_RIJNDAEL_256, $salt, $text, MCRYPT_MODE_ECB, mcrypt_create_iv

(mcrypt_get_iv_size(MCRYPT_RIJNDAEL_256, MCRYPT_MODE_ECB), MCRYPT_RAND))));
    }

//DECRYPTION

//DECRYPTION

function decrypt($text, $salt = '') {
        if ($text == "")
            return "";
        if ($salt == "")
            $salt = 'DiAo74dOO09T48YESmuvbS0T';
        return trim(mcrypt_decrypt(MCRYPT_RIJNDAEL_256, $salt, base64_decode($text), MCRYPT_MODE_ECB, mcrypt_create_iv

(mcrypt_get_iv_size(MCRYPT_RIJNDAEL_256, MCRYPT_MODE_ECB), MCRYPT_RAND)));
    }

"AFdT9sa81krHkp/GoYCSwh7/lZn/gLZLHJSldi5/QCU ="我已经使用上述加密功能对该字符串进行了加密，但是我希望它使用OPENSSL对其进行解密.我使用以下代码对其进行解密.

"AFdT9sa81krHkp/GoYCSwh7/lZn/gLZLHJSldi5/QCU=" This String I had encrypted using above encryption function, But I want it to decrypt it using OPENSSL. I used following code to decrypt it.

    $string = 'AFdT9sa81krHkp/GoYCSwh7/lZn/gLZLHJSldi5/QCU=';
    $output = false;
    $secret_key = 'DiAo74dOO09T48YESmuvbS0T';
    $secret_iv1 = openssl_random_pseudo_bytes(openssl_cipher_iv_length('AES-256-ECB'));
    $secret_iv = bin2hex($secret_iv1);
    $key = hash('sha256', $secret_key);
    $iv = substr(hash('sha256', $secret_iv), 0, 16);

    $output = base64_encode(openssl_encrypt($string, 'aes-256-ecb', $key, OPENSSL_RAW_DATA));

我希望解密输出为:"durhs-14767-w0163j1-89047"预先感谢您的答复.

I want decrypted output as : "durhs-14767-w0163j1-89047"Thanks in advance for your reply.

推荐答案

很遗憾，您的方法有误.

Saddly, you are on the wrong way.

请参阅:

http://php.net/manual/en/function. mcrypt-encrypt.php#117667

https://en.wikipedia.org/wiki/Advanced_Encryption_Standard

因此，您不能使用OpenSSL的AES-256解密MCrypt的输出.

So you can not use OpenSSL's AES-256 to decrypt the MCrypt's output.

一些可能的方法:

1. 继续使用PECL的mcrypt扩展名使用mcrypt(幸运的是，它仍然存在)，直到您可以完全替换旧数据为止.

1. Keep using mcrypt by PECL's mcrypt extension (luckily, it is still there), until you can replace the legacy data totally.

用PHP重写正确的RIJNDAEL-256密码.
