HTTP and HTTPS

Explore the main differences between HTTP and HTTPS and understand why HTTPS is getting faster and faster in all aspects

HTTP (Hypertext Transfer Protocol) Is the protocol that powers the network.

It is on top of TCP, and TCP is on top of IP.

Web pages can use HTTP or HTTPS (Hypertext Transfer Protocol Security).

How are they different? And, why does the Chrome browser now mark HTTP as insecure?

Safety

When you request an HTTP page from a server, the data will be transmitted through many different networks, each of which is controlled by a separate company or entity.

Starting with a WiFi router that may be owned by a coffee shop or a city’s public network infrastructure, every node in the network can see the request and response and can modify it in any way.

They may inject advertisements, they may inject malware, and they may record all the credentials you enter. The server in the middle can play the role of the middleman and send the corrupted information.

This also applies to any insecure internet protocol.

HTTPS traffic is end-to-end encrypted, which means that nothing between them can read the information exchanged between you and the server on the other end of the network.

port

By default, HTTP provides services through port 80, while HTTPS provides services through port 443. These are the default ports, but the web server can choose to provide content on other random ports. In this case, you need to enter the address bar:

http://flaviocopes.com
http://flaviocopes.com:80/javascript
https://flaviocopes.com:8081/javascript

Is HTTPS slow?

Do not! in contrast.

There is a myth about page speed. People think that the TLS handshake required for HTTPS slows down the page speed, but in fact, HTTPS pages can be loaded in a way,A faster way than HTTP.

why? becauseHTTP/2, Is the latest version of the HTTP protocol. HTTP/2 can process requests in parallel, andClaimSecure connection, so if your server uses a modern web server that supports HTTP/2, your web pages will experience obvious speed bumps when using HTTPS.

HTTP/2 introduces better parallelism, multiplexing and compression, which is a great update to HTTP.

Does HTTPS affect SEO?

Yes it is.

in particular,Google saysHTTPS will provide you with SEO advantages.

In addition, Google will officially mark HTTP sites as insecure in its Chrome browser, which clearly shows that if you care about what Google wants and want to take advantage of, you should switch to HTTPS as soon as possible. As much as possible. The best time should be 3 years ago, and the second best time is today.

Is HTTPS difficult to implement?

Not at all. Thanks to free SSL certificates provided by Let’s Encrypt, the push for HTTPS had a huge impact and how every decent hosting provider is implementing it for free on all the accounts. Thanks to this, in 2018 HTTPS connection is larger than HTTP connection.

In the past, providing an SSL certificate for your site was an advanced option, and few people were willing to buy it for a regular site, which neither made money nor processed user data.

Today, there are no excuses.
