decrypt static method

String? decrypt(String name, String value)

The value of the encrypted cookie name, as the browser sent it, decrypted with the APP_KEY (or one of AppConfig.previousKeys). A changed cookie, one made with another key, or one made for another cookie name gives null. req.cookie(name) uses it.

DoxCookie.decrypt('dox_session', rawValue);

Implementation

static String? decrypt(String name, String value) {
  AppConfig config = Dox().config;
  try {
    return AESEncryptor.decode(
      value,
      config.appKey,
      associatedData: name,
      purpose: KeyDerivation.cookie,
      previousSecrets: config.previousKeys,
    );
  } on DecryptException {
    return null;
  }
}
