Javascript pidCrypt RSA和PHP解密

Question

我在一个网站上工作，这个网站涉及存储公共/私有RSA加密内容，直到最近，我一直在通过javascript完成这项工作。我现在需要能够在PHP中使用公钥加密，我已经在这个问题上损失了过去6个小时。如果需要，我愿意更改库，但目前我正在尝试：

密钥：

$pub_key = "-----BEGIN PUBLIC KEY-----

使用phpseclib的PHP代码：“

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

$plaintext = 'eKFqZhGXg/QzTKI9dbvamIxDSltVWoz73DSowr87ipWHRSqKBAE463VCrcNcDKyW
gleCanPtV4NQ0qEImhf2xpIHFPeaCc++a0u7ZhZF8vpn5E8AGz97lqs3o7XGwmm1
EUlCeHh3c6574wiUd93eWBWLhxQUJPK66V3CQT0SrEQ=
';
$plaintext=base64_decode($plaintext);

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

echo $ciphertext;

只需回显空文本，明文变量就是通过pidcrypt网站使用这些密钥加密的数据。为什么这个不起作用呢？我也尝试过通过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";

也不起作用。我已经读过了，所有的东西都说pidcrypt兼容openssl。我就是想不通。

这对我来说很有效：

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

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

$ciphertext = 'B0xBiIroAo7xpHuDThpsAIAAlmlJtK1M0I4wGSJQuRMj5vy0g/+QeDYA4v+9Pl5m

$ciphertext = str_replace(array("\r","\n",' '), '', $ciphertext);
$ciphertext = base64_decode($ciphertext);

$rsa->setEncryptionMode(CRYPT_RSA_ENCRYPTION_PKCS1);

echo base64_decode($rsa->decrypt($ciphertext));

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

我猜测您做错了什么: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。
