openssl_private_decrypt()函數(shù)用于使用私鑰解密數(shù)據(jù)。
openssl_private_decrypt()函數(shù)將使用私鑰解密數(shù)據(jù)。
使用函數(shù)openssl_private_decrypt()將解密使用openssl_private_encrypt()加密的數(shù)據(jù)。
openssl_private_decrypt ( string $data , string &$decrypted , mixed $key [, int $padding = OPENSSL_PKCS1_PADDING ] ) : bool
| 序號 | 參數(shù) | 描述 |
|---|---|---|
| 1 | data | 要解密的數(shù)據(jù)。 |
| 2 | decrypted | 它將具有解密的數(shù)據(jù)。 |
| 3 | key | 私鑰。 |
| 4 | padding | 您可以應用的填充為：OPENSSL_PKCS1_PADDING，OPENSSL_SSLV23_PADDING，OPENSSL_PKCS1_OAEP_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。
要使用openssl_public_encrypt()加密數(shù)據(jù)并使用openssl_private_decrypt()解密：
<?php
//保存私鑰
$privkey = openssl_pkey_new();
openssl_pkey_export_to_file($privkey, 'C:/xampp/htdocs/modules/openssl/privatekey.pem');
//保存公鑰
$dn = array(
"countryName" => "IN",
"stateOrProvinceName" => "Karnataka",
"localityName" => "test1",
"organizationName" => "test2",
"organizationalUnitName" => "test3",
"commonName" => "www.test.com",
"emailAddress" => "xyz@test.com"
);
$cert = openssl_csr_new($dn, $privkey);
$cert = openssl_csr_sign($cert, null, $privkey, 365);
openssl_x509_export_to_file($cert, 'C:/xampp/htdocs/modules/openssl/publickey.pem');
//加密數(shù)據(jù)
$data = 'Welcome To (cainiaoplus.com)';
$isvalid = openssl_public_encrypt ($data, $crypted , file_get_contents('C:/xampp/htdocs/modules/openssl/publickey.pem'),OPENSSL_PKCS1_PADDING);
echo "Data encryption : ".$crypted;
echo ">br/<>br/<";
if ($isvalid) {
openssl_private_decrypt ($crypted, $decrypted , file_get_contents('C:/xampp/htdocs/modules/openssl/privatekey.pem'),OPENSSL_PKCS1_PADDING);
echo "Data decryption : ".$decrypted;
}
?>這將產(chǎn)生以下結(jié)果：
