Php openssl_private_decrypt不会返回任何内容,php,android,encryption,openssl,rsa,Php,Android,Encryption,Openssl,Rsa,更新： openssl\u error\u string（）给出： error:0407106B:rsa routines:RSA_padding_check_PKCS1_type_2:block type is not 02 error:04065072:rsa routines:RSA_EAY_PRIVATE_DECRYPT:padding check failed 我在服务器上使用OpenSSL生成一对公钥和私钥： $config = array( "private_k

更新：

openssl\u error\u string（）

给出：

error:04065072:rsa routines:RSA_EAY_PRIVATE_DECRYPT:padding check failed

我在服务器上使用OpenSSL生成一对公钥和私钥：

$config = array(
        "private_key_bits" => 2048,
        "private_key_type" => OPENSSL_KEYTYPE_RSA,
    );

    $res = openssl_pkey_new($config);

我将Base64编码模数和指数发送给我的Android客户端。我的Android客户端根据收到的模数和指数重建公钥。然后，我的Android客户端使用这样的密钥加密消息。最后，我的Android客户端将加密消息发送回服务器，希望服务器能够对其进行解密

我的服务器上有一个简单的PHP脚本，用于测试来自Android客户端的加密消息的解密：

$sms_message = $argv[1];
$sender_no = $argv[2];

echo "Message received was: '$sms_message' \n";
echo "sender's no was: $sender_no \n";

$parts = array();
$parts = explode(" ", $sms_message);
if (count($parts)==2) {
    echo "code: $parts[0] \n";
    if (strcmp($parts[0], "smscode")==0) {
        echo "measurement: $parts[1] \n";
        // retrieve the private key
        $keyArr = array();
        $keyArr = getKeys();
        //
        if ($keyArr) {
            $privateKey = $keyArr["private"];
            echo "$privateKey \n";
            // use the private key to decrypt the message
            echo openssl_private_decrypt(base64_decode($parts[1]), $decrypted, $privateKey); // this is supposed to return either TRUE or FALSE right?

            echo $decrypted;

            $decryptedMessages = "decrypted.txt";

            if (!$fh = fopen($decryptedMessages, 'a')) {
                echo "cannot open file $decryptedMessages";
                exit;
            }   

            // Write $somecontent to our opened file.
            if (fwrite($fh, $decrypted) === FALSE) {
                              echo "Cannot write to file ($decryptedMessages)";
                                          exit;
            }                 
            //                            
            fclose($fh);
        }   
    } else {
        echo "what received is not a measurement - $parts[1] \n";
    } 
} else {
    echo "sms message malformed";
}

我运行了以下命令：

正如您所看到的，

openssl\u private\u decrypt（）

不会返回任何内容，为什么？
即使我的加密/解密过程有问题，至少给出我期望的

false

OpenSSL非对称加密不适合加密大型文件，除非使用S/MIME。事实上，这就是我所尝试的：

已解码base64编码的“测量：”字段。解码的消息长度为256字节

尝试使用您使用以下openssl命令粘贴的私钥解密此256字节：

openssl rsautl-decrypt-in x.in-out明文-inkey private.key

但是，我得到了一个错误：

RSA操作错误

139982152128160:错误：0407106B:rsa例程：rsa_padding_check_PKCS1_type_2:块类型不是02:rsa_pk1.c:190:

139982152128160:错误：04065072:rsa例程：rsa_EAY_PRIVATE_解密：填充检查失败：rsa_EAY.c:616:

事实上，我用PHP本身尝试了这一点。但是，我没有对

$decrypted

进行

echo

，而是使用了

openssl\u error\u string

，它给出了上面的错误

此外，我也无法用公钥加密256字节的数据。我从openssl收到错误，指示

139870762710688:error:0406D06E:rsa例程：rsa\u padding\u add\u PKCS1\u type\u 2:数据对于密钥大小太大：rsa\u pk1.c:151:

所有这些似乎都表明OpenSSL的非对称加密技术不适用于加密大数据（在本例中，256字节足够大）。我不确定安卓客户端是如何加密它的。它也使用OpenSSL吗

但也有相关帖子介绍了如何应对。看看：

使用S/MIME加密：

RSA的一个限制是不能加密长度超过密钥大小的数据。如果需要使用RSA加密大量数据，则应使用AES（或其他对称密码）加密实际数据，然后使用RSA加密AES密钥。
