+ * It is calculated based on `SDKAppID`, `UserID`, and `EXPIRETIME` using the HMAC-SHA256 encryption algorithm.
+ *
+ * Attention: For the following reasons, do not use the code below in your commercial application.
+ *
+ * The code may be able to calculate UserSig correctly, but it is only for quick testing of the SDK’s basic features, not for commercial applications.
+ * `SECRETKEY` in client code can be easily decompiled and reversed, especially on web.
+ * Once your key is disclosed, attackers will be able to steal your Tencent Cloud traffic.
+ *
+ * The correct method is to deploy the `UserSig` calculation code and encryption key on your project server so that your application can request from your server a `UserSig` that is calculated whenever one is needed.
+ * Given that it is more difficult to hack a server than a client application, server-end calculation can better protect your key.
+ *
+ * Reference: https://cloud.tencent.com/document/product/647/17275#Server
