HTTPS stands for Hyper Text Transfer Protocol Secure, which in Portuguese means "Secure Hypertext Transfer Protocol".
Currently, this is the safest version of the data transfer protocol between computer networks on the internet, as it encrypts the data provided, it requires server authentication, among other tools that guarantee the security of the data sent and received by the user.
HTTPS is the combination of HTTP and SSL protocols (Secure Sockets Layers, in English).

This protocol appears before the electronic address of the website that the user wants to access (URL), ensuring that it is about a secure data connection between the user's computer and the servers that host the websites accessed.
Sites that are accessed from a secure hypertext transfer protocol appear with the code “ https://” before the URL.

The main difference between an HTTP protocol and HTTPS is precisely in the encrypted communication of the latter, which helps to avoid possible attempts to information theft during data transmission between the user's computer and the servers of the websites.
However, HTTPS connections are not completely secure, requiring the presence of software for Internet Security installed on your computer, in addition to always being on the lookout for suspicious connections.
