openssl_pkey_get_private()函數(shù)用于獲取私鑰。
openssl_pkey_get_private()函數(shù)將返回您的私鑰。
函數(shù)openssl_pkey_get_private()從給定的公鑰/私鑰返回私鑰。例如.pem文件中的內容。
openssl_pkey_get_private ( mixed $key [, string $passphrase = "" ] ) : resource
| 序號 | 參數(shù) | 描述 |
|---|---|---|
| 1 | key | 您可以從.pem文件中獲取密鑰，也可以使用openssl_pkey_new()生成的私鑰。 |
| 2 | passphrase | 如果指定的密鑰已被加密了(受密碼保護)，可選參數(shù) passphrase 是必須要的 |
如果沒有錯誤，PHP openssl_pkey_get_private()函數(shù)將返回資源標識符。如果密鑰生成失敗，它將返回false。
此函數(shù)將從大于5.0.0的PHP版本開始工作。
openssl_pkey_get_private()的工作：
<?php
//生成新的私鑰(和公鑰)對
$privkey = openssl_pkey_new();
openssl_pkey_export($privkey, $yourprivatekey);
$testprivatekey = openssl_pkey_get_private($yourprivatekey);
if ($testprivatekey === false) {
var_dump(openssl_error_string());
} else {
var_dump($testprivatekey);
}
?>這將產生以下結果：
resource(3) of type (OpenSSL key)
openssl_pkey_get_private() 和 openssl_pkey_get_details()的工作-
<?php
$privkey = openssl_pkey_new();
openssl_pkey_export($privkey, $yourprivatekey);
$testprivatekey = openssl_pkey_get_private($yourprivatekey);
if ($testprivatekey === false) {
var_dump(openssl_error_string());
} else {
//var_dump($testprivatekey);
$key_details = openssl_pkey_get_details($testprivatekey);
print_r($key_details);
}
?>這將產生以下結果：
