openssl_pkey_get_private()函数用于获取私钥。
openssl_pkey_get_private()函数将返回您的私钥。
函数openssl_pkey_get_private()从给定的公钥/私钥返回私钥。例如.pem文件中的内容。
openssl_pkey_get_private ( mixed $key [, string $passphrase = "" ] ) : resource
序号 | 参数 | 描述 |
---|---|---|
1 | key | 您可以从.pem文件中获取密钥,也可以使用openssl_pkey_new()生成的私钥。 |
2 | passphrase | 如果指定的密钥已被加密了(受密码保护),可选参数 passphrase 是必须要的 |
如果没有错误,PHP openssl_pkey_get_private()函数将返回资源标识符。如果密钥生成失败,它将返回false。
此函数将从大于5.0.0的PHP版本开始工作。
openssl_pkey_get_private()的工作:
<?php //生成新的私钥(和公钥)对 $privkey = openssl_pkey_new(); openssl_pkey_export($privkey, $yourprivatekey); $testprivatekey = openssl_pkey_get_private($yourprivatekey); if ($testprivatekey === false) { var_dump(openssl_error_string()); } else { var_dump($testprivatekey); } ?>
这将产生以下结果:
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); } ?>
这将产生以下结果:

<?php //创建私钥 $privkey = openssl_pkey_new(); openssl_pkey_export_to_file($privkey, 'C:/xampp/htdocs/modules/openssl/fortesting.pem'); //使用带有私钥的.pem文件。 $testprivatekey = openssl_pkey_get_private(file_get_contents('C:/xampp/htdocs/modules/openssl/fortesting.pem')); if ($testprivatekey === false) { var_dump(openssl_error_string()); } else { //var_dump($testprivatekey); $key_details = openssl_pkey_get_details($testprivatekey); print_r($key_details); } ?>
