我正在一个涉及存储公共/私有 RSA 加密内容的网站上工作，直到最近我一直在通过 javascript 完成这一切。我现在需要能够用 PHP 中的公钥加密，我已经失去了过去 6 个小时来解决这个问题。如果需要，我愿意更改库，但目前我正在尝试这个：

键：

/*

使用 phpseclib 的 PHP 代码："

$rsa = new Crypt_RSA();
//extract($rsa->createKey());

$plaintext = 'eKFqZhGXg/QzTKI9dbvamIxDSltVWoz73DSowr87ipWHRSqKBAE463VCrcNcDKyW
gleCanPtV4NQ0qEImhf2xpIHFPeaCc++a0u7ZhZF8vpn5E8AGz97lqs3o7XGwmm1

';
$plaintext=base64_decode($plaintext);

$rsa->loadKey($priv_key);
$rsa->setEncryptionMode(CRYPT_RSA_ENCRYPTION_PKCS1);
$ciphertext = $rsa->decrypt($plaintext);

echo $ciphertext;

只是回显空文本，纯文本变量是使用这些密钥通过 pidcrypt 网站加密的数据。为什么这不起作用？我也试过通过openssl运行它：

$res = openssl_get_privatekey($priv_key);
/*
* NOTE:  Here you use the returned resource value
*/
openssl_private_decrypt($plaintext,$newsource,$res);
echo "String decrypt : $newsource";

也没有工作。我读过并且everythibng 说pidcrypt 是openssl 兼容的。我似乎无法弄清楚。

这对我有用：

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

$rsa = new Crypt_RSA();
$rsa->loadKey('-----BEGIN RSA PRIVATE KEY-----

$ciphertext = 'B0xBiIroAo7xpHuDThpsAIAAlmlJtK1M0I4wGSJQuRMj5vy0g/+QeDYA4v+9Pl5m

这是在https://www.pidder.de/pidcrypt/?page=demo_rsa-encryption使用默认的公钥/私钥对。密文也来自该页面。

我对您做错了什么的猜测：您正在从“加密文本”文本框中复制/粘贴文本，但没有删除换行符。
