我正在尝试使用 PHP 和 OpenSSL 使用公钥加密一些数据,然后再次解密。
我使用以下代码生成了 public.key 和 private.key:
// generate private key
$privateKey = openssl_pkey_new(array(
'private_key_bits' => 1024,
'private_key_type' => OPENSSL_KEYTYPE_RSA,
));
// write private key to file
openssl_pkey_export_to_file($privateKey, 'private.key');
// generate public key from private key
$publicKey = openssl_pkey_get_details($privateKey);
// write public key to file
file_put_contents('public.key', $publicKey['key']);
// clear key
openssl_free_key($privateKey);
我的加密和解密代码基本上直接来自 PHP 文档:
// data to encrypt
$data = "This is a long string or other bit of data that i want to encrypt";
// ==== ENCRYPT ====
// read public key
$publicKey = file_get_contents("public.key");
$publicKey = openssl_get_publickey($publicKey);
// encrypt data using public key into $sealed
$sealed = '';
openssl_seal($data, $sealed, $ekeys, array($publicKey));
openssl_free_key($publicKey);
// ==== DECRYPT ====
// get private key to decrypt with
$privateKey = file_get_contents("private.key");
$privateKey = openssl_get_privatekey($privateKey);
// decrypt data using private key into $open
$open = '';
openssl_open($sealed, $open, $env_key, $privateKey);
openssl_free_key($privateKey);
// display decrypted data:
echo "<p>Decrypted data: ".$open;
任何人都知道为什么它不起作用,或者至少有一种方法可以找出发生了什么错误?
