Basic difference between HTTP and HTTPS protocols

What was before, https or https?

At the beginning of the network protocols, network administrators had to figure out how to share the information they put on the Internet. They agreed on a procedure for exchanging information and called the system HyperText Transfer Protocol (HTTP). When the exchange of information began​, interception on the Internet was not difficult. Thus, the expert administrators agreed on the procedure for protecting the information they exchanged. Protection relies on SSL certificate for encrypting network data. Encryption means that the sender and receiver agree to the “code” and translate their documents into strings of characters that appear random. The process to encrypt the data and then exchange the data is called HyperText Transfer Protocol Secure (HTTPS).

Decryption

With HTTPS, if someone between sender and receiver can open a message, it still can't be decrypted. Only the sender and the recipient, who know the code, can decrypt the message. People could encode their own documents, but computers do it faster and more efficiently. At each end, the computer uses a document called the “SSL certificate”, which contains characters that are keys to their secret “codes”. SSL certificates shall contain ’public keythe owner of the computer. The owner shares a public key with whom he needs it. The owner sends these users an SSL certificate containing this public key and the key is not shared with other users.

Protocol security

Security during transmission is called Secure Sockets Layer (SSL) and Transport Layer Security(TLS). The procedure for exchanging public keys using SSL certificates to enable HTTPS, SSL and TLS is called public key infrastructure (PKI).

When it comes to the need to use one or another protocol, pages that are not used for data exchange generally do not need the HTTPS protocol. For this reason, search engines always say in the header: not secure. HTTPS protocol is required when data exchange pages are created and such pages do not differ in functionality from pages with HTTP protocol, unless there are several users on the pages at the same time. In this case, the page loaded somewhat slower.

Meaning of protocol to the client of the website?

Therefore, when creating a website, the client should be suggested and even set as a mandatory use of the SSL protocol in order to make a quality website along with other parameters of optimal parameters on the site. HTTPS is a protocol for which Google has given an explanation that it gives a better SEO ranking on the search engine, and according to the latest information the site without HTTPS protocol will be significantly worse in search ranking.

In the future, all pages will gradually switch to the HTTPS protocol. And now those who have these pages on the HTTP protocol switch to the HTTPS protocol can do painlessly. There is only the possibility that on some hosting services the SSL certificate is not free. Therefore, when placing a site on a hosting site, this information should be checked beforehand.

Does domain extension have anything to do with https?

No, domain extension is irrelevant to https protocol. As it is here see, domain extension is essential primarily because of the subjective experience and preferences of displaying the website. Https protocol can be applied in any domain.
