我正在尝试解密PHP中的私钥数据。但是我的回复显示私钥无效。我尝试了很多其他选择，但没有帮助。首先，我至少需要最简单的示例来了解如何在 PHP 中解密数据。我的代码：
$privateKey = openssl_get_privatekey(base64_encode('-----BEGIN RSA PRIVATE KEY-----

$source='BcIBgKb3NjvQ6YsmzpE5vTZnwGJnAyLZGDFei254aHRjvOyFgVakNj7R9RAOnKaLUWaw6cRGRyGWOQuGU3wZHBIO36vpQvEh+rLZszIKO2zb5NSKXYnQIzt4LJn2aEK3fXwk7ADXSxAeBC+pB+59ADxBvBbehmBK7t2W7pPPCro=';
openssl_private_decrypt(base64_decode($source),$newsource,$privateKey);
echo "String decrypt : $newsource";
您需要
删除第一行中的base64_encode函数。
$privateKey = openssl_get_privatekey ('----- BEGIN RSA PRIVATE KEY -----
...
...
...
----- END RSA PRIVATE KEY ----- ');
