Question

我尝试使用openssl_private_encrypt加密某些文本，但函数返回FALSE并且不加密任何内容。

我制作了两个版本的代码

$result = $stmt->get_result();
if($result)
{
    while($rows = $stmt->fetch_assoc())
    {
    //Code here 
    }
}

和

//$privateKey = file_get_contents(__DIR__.'/key_dev_exe_1k.pem');
$privateKey = openssl_pkey_get_private(__DIR__.'/key_dev_exe_1k.pem');
var_dump(openssl_private_encrypt($referrer_string, $crypted, $privateKey));
var_dump(array($referrer_string, $crypted, $privateKey)); exit();

第一个输出包含警告。

警告：openssl_private_encrypt（）：key param不是有效的私有键

第二个输出没有任何警告，但显示加密函数返回FALSE。

$privateKey = file_get_contents(__DIR__.'/key_dev_exe_1k.pem');
//$privateKey = openssl_pkey_get_private(__DIR__.'/key_dev_exe_1k.pem');
var_dump(openssl_private_encrypt($referrer_string, $crypted, $privateKey));
var_dump(array($referrer_string, $crypted, $privateKey)); exit();

key_dev_exe_1k.pem在同一目录中。

这对我有用

//index.php
$data = "Hello World";
$fp = fopen("keys/doe.key","r");
$priv_key = fread($fp, 8192);
fclose($fp);
openssl_private_encrypt($data, $crypttext, $priv_key);
echo $crypttext;

//doe.key
