我无法使用加密类(它位于classes文件夹中的单独文件中)。该类的代码是:
class SymmetricCrypt
{
// Encryption/decryption key.
private static $msSecretKey = "Hello";
// The initialisation vector.
private static $msHexaIv = "c7098adc8d6128b5d4b4f7b2fe7f7f05";
// Use the Rijndael Algorithm.
private static $msCipherAlgorithm = MCRYPT_RIJNDAEL_128;
public static function Encrypt($plainString)
{
$binary_iv = pack("H*", SymmetricCrypt::$msHexaIv);
// Encrypt source.
$binary_encrypted_string = mcrypt_encrypt(SymmetricCrypt::$msCipherAlgorithm, SymmetricCrypt::$msSecretKey, $plainString, MCRYPT_MODE_CBC, $binary_iv);
// Convert $binary_encrypted_string to hexadeciaml format.
$hexa_encrypted_string = bin2hex($binary_encrypted_string);
return $hexa_encrypted_string;
}
public static function Decrypt($encryptedString)
{
$binary_iv = pack("H*", SymmetricCrypt::$msHexaIv);
// Convert string in hexadecimal to byte array.
$binary_encrypted_string = pack("H*", $encryptedString);
// Decrypt $binary_encrypted_string,
$decrypted_string = mcrypt_decrypt(SymmetricCrypt::$msCipherAlgorithm, SymmetricCrypt::$msSecretKey, $binary_encrypted_string, MCRYPT_MODE_CBC, $binary_iv);
return $decrypted_string;
}
}
这就是我打电话给班级的方式:
require_once 'classes/symmetric_crypt.php';
$sc = new SymmetricCrypt();
$password = "password";
$ec_password = $sc->Encrypt($password);
... insert into database.
如果我回显$ password的内容,则显示“password”。如果我回显$ ec_password,它什么也不返回。
我以前在不同服务器上的其他项目中使用过它。它可能与服务器有关吗?还有其他想法吗?
谢谢,
阿德里安
