What is the mainstream data transmission encryption method in the industry now?

There are people cheating in my game

No one can give you a direct answer to your statement. First, at which level of the system is the hang?

Does the Tencent cloud hosting I use have encryption components?

Plugins usually modify the front-end memory data or modify the network communication data. If the network communication data uses SSL, it has encryption function. If it is still cracked, there seems to be no good way. Adding another layer of encryption at the user level requires the front-end and back-end agreement. If someone with ulterior motives cracks the front-end and gets the secret key from it, the encryption will be useless. Another way is that the back-end sends the secret key when logging in, and all communications after logging in are encrypted and decrypted with this secret key. This secret key can only be used for encryption and decryption of this user’s communication.

Isn’t it normal to cheat? If there is a problem, it is because the backend has no restrictions.

Generally, no one uses the method of cracking network data packets to cheat. Generally, the game API is called directly. The terminal game is the call function address, and H5 should be the call of JS code.
