+ * AES-256-GCM 加密解密工具类
+ * 
+ * 安全设计说明：
+ * - 使用 AES-256-GCM 提供认证加密（AEAD）
+ * - GCM 模式自动提供认证标签（tag），防止数据被篡改
+ * - IV（初始化向量）长度为 12 字节（96位），符合 GCM 推荐
+ * - 认证标签长度为 16 字节（128位），提供强认证
+ * - 加密数据格式：IV (12字节) + Ciphertext (变长) + Tag (16字节)
+ * 
+ * 为什么第三方无法伪造：
+ * - 只有拥有正确 licence + fingerprint 的设备才能派生正确的 AES 密钥
+ * - GCM 模式会验证认证标签，任何篡改都会导致解密失败
+ * - 即使第三方获取了加密数据，也无法解密（缺少密钥）
