HTTPS is a more secure HTTP protocol. It adds an SSL layer between TCP (responsible for network data transmission) and the HTTP layer. This layer encrypts HTTP requests through digital certificates and encryption algorithms. Full-network HTTPS means encrypting and protecting every page of the entire website, allowing visitors to browse under the protection of the HTTPS protocol throughout the process.

In 2017, the global HTTPS encrypted traffic continued to grow. In the requirements for data security in all fields around the world, HTTPS encryption has been listed as an essential standard. Google has stricter requirements for website encryption. Since last year, it has required all major platform websites to add the HTTPS protocol. Recently, it even announced a "ban" on HTTP.
