The difference between HTTPS and HTTP and selection suggestions. Is it necessary to use HTTPS when building a website?

Nowadays, most of our webmasters will definitely choose HTTPS more when building websites. After all, whether we use a free SSL certificate or a paid certificate, the basic technical aspects and cost budget considerations can still be satisfied. The reason why we did not choose HTTPS in the early years was largely because HTTPS configuration was too troublesome, and sometimes certificates needed to be purchased. Therefore, in Snail Blog, Snail has written many HTTPS configuration tutorials for a long time. But I haven't installed HTTPS yet, so many netizens left contemptuous messages saying that you haven't installed HTTPS yourself.

In the past few days, when discussing the difference between http and https with netizens, the necessity of installing a certificate was mentioned. Because we have seen that some older websites, and of course very good individual webmasters, do not use SSL certificates to implement HTTPS encryption. The reason why the webmaster was asked is that they were worried that there would be problems with the inclusion after changing to HTTPS, so they never changed it. Although they knew that some networks were hijacked, they had no choice but to dare to change it.

First, the difference between http and https

Here at Snail Blog, we will not introduce overly technical issues, such as the differences between various SSL certificates, the layered technology filtering encryption we use when choosing HTTP and HTTPS, etc. These are too complicated. Ordinary users can’t understand it, and they don’t want to read it. Many of our users are concerned about the difference between using HTTP and HTTPS, and even whether there are any benefits.

For commercial websites, if we use HTTPS, it will indeed encrypt information transmission. Sometimes we can’t feel it when we are not doing commercial websites. Some people can use non-HTTPS or SSL certificates that are not strongly encrypted can hijack user data or we have seen cases of DNS hijacking and redirection.

If we use HTTP or an SSL certificate without strong filtering mechanism, this problem may occur. So we can see the difference between EV SSL certificates or other certificates. In fact, there are differences in encryption levels, not just the price and domain name restrictions that our users see.

Using HTTP uses port 80, while HTTPS uses port 443. Of course we all need to be open to users. As for browsers, we see that most browsers require an SSL certificate so that there is trust. Otherwise, it will prompt that the website is not trusted. If it is an ordinary personal website, it certainly does not matter. What if it is a commercial website? What do users think?

Second, is there any impact of not using HTTPS?

If we are an English website or mainly engaged in Google search engine, then Snail still recommends that we install HTTPS encryption mode, because according to the policy, we have seen before that if the website uses SSL certificate, it will have extra points in Google search engine. of. If we are using a Chinese website, choose it according to the situation. I saw some webmasters mentioned that using HTTP is better for collection and convenience, while HTTPS collection will be slower.

From a user perspective, when we use HTTPS, the delay may be slightly longer and the HTTP response speed will be faster. If we are a personal website, if you plan to hold it for a long time and don’t want to have trouble in the future, then just use HTTPS. If we used HTTP in the early days, the current website weights are all good, so I suggest you take a look first.

Of course, Snail has also encountered netizens who mentioned that their websites had adverse reactions after changing to HTTPS. However, this also depends on the quality of the website. If we can do it well, it will not be a big problem.
