Question

我是PHP加密的新手。我正在尝试使用phpseclib加密某些内容，但是由于某些原因，crypto（）函数不会返回任何内容。

这是我现在拥有的核心：

include('/pathto/Crypt/RSA.php');

$key = '-----BEGIN PUBLIC KEY-----
MIIB/TCCAWYCCQDJ7TMYJFzqYDANBgkqhkiG9w0BAQUFADBCMQswCQYDVQQGEwJjbjEVMBMGA1UE

-----END PUBLIC KEY-----';

$rsa = new Crypt_RSA();
$rsa->loadKey($key);

$sometext = 'test this text';

echo $rsa->encrypt($sometext);

我下载了1.0版。

怎么了？谢谢你。

编辑： 我更深入地发现了以下问题：https://stackoverflow.com/a/20689058/10169071 并将我的测试代码的一部分更改为此：

if (!$rsa->encrypt($sometext)) {
    echo "false";
} else {
    echo $rsa->encrypt($sometext);
}

这证明我的密码有误。但是格式应该如何？

编辑，解决方案：

$x509 = new File_X509();
$x509->loadX509($key);
$pkey = $x509->getPublicKey();

$rsa = new Crypt_RSA();
$rsa->loadKey($pkey);

echo $rsa->encrypt($plaintext);

?>

您的RSA公钥实际上是X509证书。它包含公钥，但它本身不是公钥。通过执行以下操作，我可以使您的代码示例正常工作：

<?php
include('File/X509.php');

$key = '-----BEGIN PUBLIC KEY-----
MIIB/TCCAWYCCQDJ7TMYJFzqYDANBgkqhkiG9w0BAQUFADBCMQswCQYDVQQGEwJjbjEVMBMGA1UE

-----END PUBLIC KEY-----';

$x509 = new File_X509();
$x509->loadX509($key);
$rsa = $x509->getPublicKey();

$sometext = 'test this text';

echo $rsa->encrypt($sometext);

$ rsa-> encrypt（）的公钥有问题
