Question

这是我的php脚本

<?php
$pubfile = fopen("public_key.pem", "r");
$public = fread($pubfile, 8192);
fclose($pubfile);
openssl_get_publickey($public);

$prifile = fopen("private_key.pem", "r");
$private = fread($prifile, 8192);
fclose($prifile);
openssl_get_privatekey($private);

$plaintext = "hello";

openssl_public_encrypt ($plaintext , $crypted , $public);

openssl_private_decrypt($crypted, $decrypted, $private);
echo $decrypted;
?>

我各自的公钥和私钥

private_key.pem

public_key.pem

$crypted向我返回加密数据但是解密没有回复。

我对结果做了回应，它以NULL的任何想法回来了？

Answer 1

解决。我不知道发生了什么但是在生成新的密钥对后脚本工作了。我可能混淆了我的密钥对

Answer 2

使用openssl rsa转储密钥内容会显示您在上面发布的私钥和公钥具有不同的模数。对于匹配的密钥对，私钥和公钥中的模数将相同。换句话说，你肯定会在那里混淆不同的键。

要检测到这一点，OpenSSL本身具有RSA_check_key()函数来检查RSA密钥对是否可用，但PHP wrapper for OpenSSL似乎没有向用户公开该函数。

公钥：

% openssl rsa -in public_key.pem -pubin -text
