6 free SSL certificate application cost saving configuration websites HTTPS encryption website

In the past, if we need to configure SSL certificates for websites, the cost is quite high. The main reason is that businesses have not yet popularized and provided SSL certificates, but now both paid and free SSL certificates are quite popular. We should know that Votone's free SSL certificate (currently not free) StartSSL、Let's Encrypt， At present, many IDC merchants in China provide Symantec DV SSL certificates for free.

However, there have always been disputes about the compatibility of Symantec SSL certificate and Chrome. If Chrome abolishes all Symantec certificate support, it will actually have an impact on the website, especially the number of users of overseas websites is still large. We can pay attention to the development of the situation. If the project is important, it is recommended to use a paid SSL certificate.

In this article, Lao Zuo sorts out some free SSL certificates he has seen so far. If you need to reduce the cost of configuring HTTPS encryption for websites, you can choose to use them.

First, Let's Encrypt

Official website: https://letsencrypt.org/

There are still many supports/sponsors of Let's Encryption free SSL certificates, including Chrome. Is the dispute between it and Symantec to popularize and promote the use of Let's Encryption? Although Let's Encrypt does not offer free 1-3 years/time like some free merchants, it only has a free cycle of 90 days. We need to set up automatic or early renewal to continue using it.

Second, StartSSL

Official website: https://www.startssl.com/

The StartSSL free SSL certificate has been provided for some time. I remember trying to apply for it before. I just went to the official website to see that the 3-year free SSL service is available, but I saw some articles that mentioned that StartSSL is not trusted in Firefox. If we find that the trust is incompatible with the browser when using it, we'd better choose another one.

Third, AliCloud Symantec DV SSL

Official website address: https://www.aliyun.com/product/cas

Free DV SSL certificates. Each domain name can be applied for one year at a time, and each Alibaba account can issue 20 free certificates. Single domain name, secondary domain name, separate application is calculated separately.

Fourth, Tencent Cloud DV SSL Certificate

Official website address: https://console.qcloud.com/ssl

Similarly, a free DV SSL certificate for one year is also provided. The application is relatively simple, and can be passed as long as the domain name ownership is verified.

Fifth, Western Digital Free SSL

Application address: http://www.west.cn/web/ssl/default/index

One year free domain name DV SSL certificate, Lao Zuo tried to apply before（ here ）The delegation certificate can be obtained within 5 minutes after submission.

Sixth, Jing'an Free DV SSL Certificate

Application address: http://www.zzidc.com/main/huodong/freessl.html

Each Jing'an account can apply for three free DV SSL certificates. Laozuo seemed to see that the qualification could be delegated only after an appointment, but now it seems that he can directly submit shopping cart orders for verification free of charge. After all, most domestic IDC merchants provide free services.

In conclusion, we can see that there are still many businesses and services that provide free SSL certificates. From the perspective of compatibility and support, we have to consider all browser support. Personally, Let's Encrypt is better than Let's Encrypt for free, but the application verification for ordinary users may be slightly more complicated than that for other domestic businesses.

If a qualified friend still buys a paid certificate, I will organize an article to see the price comparison of several mainstream merchants' paid SSL certificates. If a netizen is using a paid SSL certificate, please leave a message to tell me which ones are good and the cost performance is acceptable.
