无法使用 openssl_private_decrypt 解密任何消息

Question

I try to decrypt RSA encrypted message from php with openssl_private_decrypt function.我尝试使用openssl_private_decrypt function 从 php 解密 RSA 加密消息。 But the function always return null.但是 function 总是返回 null。

My function is the following:我的 function 如下：

function (){
    $encrypted = 'gu6F7PFj2t+Mchp2Vi8dpiEXXVDkrjrSoOnRlCWeZYjOL6WdjvxULyEG5j9dZPORNMYx5eB9gTdni4NYYCKW3GTGS0zaKGgadChy/KZAUo40sBVmTFN3YOT6FfEr4oXZ9c0DqSRJ/LrZsZvsiHh52LleA9sapOgsm0bsgWzgnnE=';
    $privateKey = '-----BEGIN RSA PRIVATE KEY-----

    return openssl_private_decrypt(base64_decode($encrypted), $decrypted, $privateKey);
}

The decrypted is the following: Salut les amis解密后的内容如下： Salut les amis

You can slightly modify your code to detect the error您可以稍微修改代码以检测错误

function (){

    $encrypted = 'gu6F7PFj2t+Mchp2Vi8dpiEXXVDkrjrSoOnRlCWeZYjOL6WdjvxULyEG5j9dZPORNMYx5eB9gTdni4NYYCKW3GTGS0zaKGgadChy/KZAUo40sBVmTFN3YOT6FfEr4oXZ9c0DqSRJ/LrZsZvsiHh52LleA9sapOgsm0bsgWzgnnE=';
    $privateKey = '-----BEGIN RSA PRIVATE KEY-----

-----END RSA PRIVATE KEY-----';

    if (!openssl_private_decrypt(base64_decode($encrypted), $decrypted, $privateKey)) {
        throw new Exception(openssl_error_string());
    }
    return $decrypted;
}

The result on my machine is:我机器上的结果是：

PHP Fatal error:  Uncaught Exception: error:0407109F:rsa routines:RSA_padding_check_PKCS1_type_2:pkcs decoding error in /home/foobar/test.php:20

So, there is a "pkcs decoding error" when decoding your encrypted string.因此，在解码加密字符串时会出现“pkcs 解码错误”。 And your openssl_private_decrypt failed to decrypt your message.并且您的openssl_private_decrypt未能解密您的消息。 Please check the way you encrypted / base64_encode the text to see if you have any mistake there.请检查您加密/ base64_encode文本的方式，看看您是否有任何错误。
