Static Methods
-
decryptAES(
{required String encryptedData, required String userKey}) → String - AES-256-GCM解密
-
decryptFast(
{required String encryptedData, required String userKey}) → String - 快速解密
-
deriveKey(
{required String password, required Uint8List salt, int keyLength = 32}) → Uint8List - PBKDF2密钥派生 - 从密码生成加密密钥
-
encryptAES(
{required String plainText, required String userKey}) → String - AES-256-GCM加密 - 用于SharedPreferences 提供认证加密，防止数据篡改
-
encryptFast(
{required String plainText, required String userKey}) → String - 快速加密（使用AES-CTR模式，适合大数据）
-
generateInstallationSalt(
) → String - 生成安装时的唯一盐值（应该在首次安装时生成并保存）
-
generateTimeBasedKey(
{required String baseKey, Duration validity = const Duration(hours: 1)}) → String - 生成时间戳基础的动态密钥（可选，用于额外安全）
-
generateUserKey(
{required String userId, required String deviceId, String? additionalEntropy}) → String - 从用户特定信息生成密钥 组合多个因素确保每个用户的密钥唯一
