openssl_private_encrypt()函數(shù)用于使用私鑰加密數(shù)據(jù)。
openssl_private_encrypt()函數(shù)將使用私鑰加密數(shù)據(jù)。
使用openssl_private_encrypt()函數(shù)將對數(shù)據(jù)進行加密，并且可以使用openssl_public_decrypt()對其進行解密。
openssl_private_encrypt ( string $data , string &$crypted , mixed $key [, int $padding = OPENSSL_PKCS1_PADDING ] ) : bool
| 序號 | 參數(shù) | 描述 |
|---|---|---|
| 1 | data | |
| 2 | encrypted | 它將擁有加密的數(shù)據(jù)。 |
| 3 | key | 私鑰。 |
| 4 | padding | 您可以應(yīng)用的填充為：OPENSSL_PKCS1_PADDING，OPENSSL_NO_PADDING。 |
PHP openssl_private_encrypt()函數(shù)成功時返回TRUE，失敗時返回FALSE。
此函數(shù)將從大于5.0.0的PHP版本開始工作。
使用openssl_private_encrypt()使用私鑰加密數(shù)據(jù)：
<?php
//加密數(shù)據(jù)
$privkey = openssl_pkey_new();
openssl_pkey_export_to_file($privkey, 'C:/xampp/htdocs/modules/openssl/privatekey.pem');
$data = 'Welcome To TuorialsPoint';
openssl_private_encrypt ($data, $crypted , file_get_contents('C:/xampp/htdocs/modules/openssl/privatekey.pem'),OPENSSL_PKCS1_PADDING);
echo $crypted;
?>這將產(chǎn)生以下結(jié)果：
