Hypertext transfer protocol secure or HTTPS is a secure version of the HTTP protocol that is responsible for transferring data between the browser and the server. HTTPS enhances the security of data transmitted between the browser and the server by encrypting it. This is especially important when sensitive data such as bank account information, email account information, or health information is being transmitted, such as sites that use individuals’ banking information, such as payment gateways and interfaces. . These payment sites are required to use HTTPS.
What is the difference between HTTP and HTTPS?
HTTPS is the same as HTTP except that TLS encryption is applied to it. HTTPS uses TLS, or SSL, to encrypt HTTP requests and responses to increase their security.
Sites that use HTTPS The domain of their site starts with https: // like https://wikidemy.ir.
Why should we use HTTPS?
The first reason: Sites that use HTTPS are more reliable.
A site that uses HTTPS is like a restaurant that meets all safety and health standards. When a restaurant has these standards, customers can more easily trust them, because they are sure that they are eating healthy and fresh food. Indeed, today, sites that still use HTTP are like restaurants that have worn out and failed a passing test. So if someone prepares food from these restaurants, he accepts the risk of unhealthy food and may get sick.
HTTPS uses the SSL / TLS protocol to encrypt communications, so a hacker cannot hack this data and view the data inside. SSL / TLS also prevents authentication and then checks that the request to the server is from you or a third party. This prevents hacking and theft of information (such as a restaurant that meets health standards and you do not get sick)
Although some users do not know the benefits of TLS and SSL, today’s browsers can easily detect these and if a site does not use the https version, it will warn the user about insecurity on this site.
Chrome and other browsers identify sites that use HTTP as “insecure.”
Google has also taken steps over the years to encourage sites to use HTTPS. Google added HTTPS to SEO factors . The more secure the website, the less mistakes a user will make in deciding on the links that Google offers.
From July 2018 and after the Chrome update to version 68, Chrome separated all sites that used HTTP from other sites by marking it as “Not Secure”. This alert is displayed for all sites that do not use SSL. Other companies have followed suit and added this feature to their browsers.
Second reason: Sites that use HTTPS provide more security for users and site owners.
With HTTPS, data is encoded in two ways: the path that the data goes to the main server and the return path where the data is routed from the main server to the user. In this case, hackers can no longer view the data in this path. As a result, when you enter your username or password in a form and send it to the server, hackers can not steal it. If websites or web applications have to send sensitive or personal data to users, such as bank account information, data encryption can protect that data well.
Third reason: HTTPS authenticates sites.
Users who use online taxi apps like Ola and uber do not have to get in that car just because the driver tells them I am from ola or uber Because the software displays information about the driver such as the driver’s image and name, car type and license plate to the user. The user can choose the right car and ride it by matching the software and driver and car information, even if he has not seen that car in his whole life.
The same thing happens with users who visit a website. In fact, they are connected to a very distant computer that they do not know where it is, a computer by a person whom the user has never seen before. The SSL certificate, which enables HTTPS, is similar to the driver information in online taxi software, and does the authentication of the web server by performing certain tasks. As a result, no one can forge a site like another to defraud users.
SSL authentication appears on the websites of most companies in the world today and has a great impact on people’s trust in that company.

Misconceptions about HTTPS
Many sites need time to adapt to https. Let’s look at history to find the source of this problem.
When HTTPS was launched, its basic setup was hard, slow, and expensive; That is, it was difficult to execute properly, slowed down Internet applications, and increased costs by obtaining a service certificate. But this is no longer true today. But there are fears that still exist in the hearts of website owners and do not allow them to decide to launch https on their website. Let me tell you some of these misconceptions that cause fear.
- I do not have sensitive information on my site, so I do not need https
One of the reasons that website owners are not interested in increasing the security of their site is that they think that engaging in security at this stage of their business will take them away from their goal. After all, if you are not dealing with sensitive data, then what does all this hacking and data loss mean? Here are some reasons for web security. Some ISPs are forced to inject their ads into http-based sites. These ads may be displayed in the text and may be displayed next to the site, but the truth is that the site owner does not benefit from these ads. But once you were securing your site, no one could force their ads into your site.
Modern browsers today have restrictions on sites that are not secure. Currently one of the features that increases the quality of the site is the use of HTTPS. Today’s new technologies, such as user geolocation and push notifications, also require the use of progressive web software (PWAs), all of which require a high level of security. It feels like data like user’s location has to be very sensitive so it can also be used for malicious purposes.
- I do not want to interfere with my site performance by increasing page load time
Site performance is one of the most important SEO factors for Google as well as user experience. Increasing page load time is also understandable. Fortunately, over time, improvements have been made to HTTPS to reduce the time required to create an encrypted connection.
- What is Google’s caffeine algorithm?
But when an HTTP connection is established between the server and the user, many connections are needed to direct the request from the user to the server and from the server to the user. In addition to the delay caused by the TCP connection marked in blue in the image, a TLS / SSl connection (modified by handshake) marked in yellow in the image must also occur in order to use HTTPS.
Private solutions can reduce this interrupt by connecting to ssl.
- Using HTTPS will be expensive for me
This may seem right at first, but now the cost is no longer there. Because you are creating a secure layer of data transfer, your customers will trust you more. In addition, when you use HTTPS for your site, Google and other search engines will give you a positive rating and will ultimately have a good effect on your SEO.
- When I switch my site to HTTPS, my site ranks lower in search engines
There are risks when moving the site and if this is not done properly, it can have a negative impact on SEO. Possible problems include website crashes and downs, crawled pages and penalties for duplicate content that may be on two or more pages of your website. Therefore, when transferring your site to HTTPS, be very careful or ask an expert to do it for you.
Two of the best ways to get your site to HTTPS are:
- Use Redirect 301
Using a 301 redirect to an HTTP site to point to its HTTPS version, your website tells Google that all pages on your site must be moved to a new location to be indexed and displayed in searches.
- Proper displacement of canonical tags
Using the canonical tag on HTTPS sites, crawlers like the googlebot understand that they must follow secure pages from now on.
If you have a large number of pages and you are worried that it will take a long time to crawl your pages again, contact Google and tell them how much traffic you expect to generate through your website. Network engineers then increase the crawl speed of your site to get your pages indexed faster.
