Question

phpseclib：

php代码：

include('Crypt/RSA_XML.php');

$rsa = new Crypt_RSA_XML();

$rsa->loadKeyfromXML($public_key_xml);

$data = "invoice_number=1,100.00&customer_tin=674858994885&serial=ONLYPEMPSERIAL&tin=ONLYPUMPTIN&vat_1_net=2,0000&vat_1_value=3600&vat_2_net=0&vat_2_value=0&vat_3_net=0&vat_3_value=0&vat_4_net=0&vat_4_value=0&vat_5_net=0&vat_5_value=0&vat_6_net=0&vat_6_value=0&vat_7_net=0&vat_7_value=0&vat_8_net=0&vat_8_value=0&payment_mode=3&discount=200&total_gross=9562";
$plaintext = $data;

//define('CRYPT_RSA_PKCS15_COMPAT', true);

$rsa->setEncryptionMode(CRYPT_RSA_ENCRYPTION_PKCS1);

$ciphertext = base64_encode(strrev($rsa->encrypt($plaintext)));

echo "data";

echo $ciphertext; // there is encoded value getting

和那么如何使用私钥解密加密数据： echo $ rsa-＆gt; decrypt（$ ciphertext）; //这是错误，解密错误

实际上，我想在php中加密并在c＃中解密，数据加密成功，当c＃rsa加密服务解密此加密数据，然后给出错误消息：无效的base-64字符串长度

$public_key_xml and $private_key_xml is defined below...

Answer 1

你必须使用一个非常老的版本的phpseclib，因为phpseclib已经内置了对XML格式的支持已经有好几年了。所以我的第一个建议是升级到最新版本。之后你应该能够做到这样的事情：

<?php
include('Crypt/RSA.php');

$plaintext = 'zzz';

$rsa = new Crypt_RSA();
$rsa->loadKey('<RSAKeyValue>        
    <Modulus>uidt3bPfWozkIkC6nHnRDbXrvjqplfCslV2zP4hKJ6sVjVnPfjMM0ueCuEDFZ9NK+kCWaPNAVhOKKwL8HmoX/7KcFLWkwSoatnrncHTH5STey+bqR1xTFY+Rubj8BZt7D9JJYyLQC46wn4ySVnLWkCZZ9+aaTriEBzGTpUzeRiUTWVprp3oXsA7ZKyn+lhZfMx1ILhcD8dnX7xFHB57jIKvPBxAdT4K7GxdgENeS76I/zmVmlF//JnmtZ/RM1WmRkx8mFmcK/Ky8gLsmIpPPltoyBWIKIf2NQH9kHqHa2gwoPg34LTutV9AACTWuiVOjqU7Gq2BHQcjovXMF8t3Wiw==</Modulus><Exponent>AQAB</Exponent></RSAKeyValue>');

define('CRYPT_RSA_PKCS15_COMPAT', true);

$rsa->setEncryptionMode(CRYPT_RSA_ENCRYPTION_PKCS1);

echo base64_encode($rsa->encrypt($plaintext));

如果这不起作用，它有助于查看您用来解密的.NET代码。此外，如果您可以在.NET中加密字符串并发布用于加密的公钥以及有用的密文本身。从那以后我可以使用phpseclib选项，直到我找到一些选项组合让我解密字符串，这可能反过来让我们深入了解如何加密字符串。

使用rsa公钥和私钥使用phpseclib加密和解密，获得解密错误
