Google announced in 2014 that websites using HTTPS encryption will help search rankings. Of course, the main reason is that all links from the search results are safe. It is always reassuring to see a website with an SSL certificate icon next to the browser’s address bar. When a website has SSL certification, it means there is a secure channel to ensure that the personal information entered by Internet users is protected from interception or tampering by hackers. However, there is a fee to obtain an SSL certificate. Previously, I used the 90-day free version. Fortunately, it will automatically update when the time comes, so you don’t have to worry about certificate expiration. If you are worried about whether the website’s SSL certificate has expired, try LetsMonitor’s free SSL monitoring service. In addition to viewing relevant information, reminder notifications will also be sent before expiration!
Before applying for a certificate, try using the https network security transmission protocol. Sure enough, it tells you that there is a problem with the security certificate of your website, which means that all data passing between the server and the browser is not guaranteed to be safe.
What is SSL (Secure Sockets Layer) certificate service? It is mainly used to establish a secure channel between the browser and the website server. It can provide server authentication and data transmission encryption. The SSL authentication mechanism provides a secure channel to ensure that personal information entered by Internet users is protected from interception or tampering by hackers.
If you see a “Security” lock on the address bar, it means that the information sent or received through the website will not be made public. Of course, seeing this lock icon does not mean you can sit back and relax. You must still be vigilant when sharing private information. After all, it may be a phishing webpage. Always make sure that the website you are on is indeed the website you want to visit.
Sure enough, I saw the issuer of the certificate information, who it was issued to, and the validity date. I used free Cloudflare’s SSL. There are a lot of teaching instructions on Google.

However, the free LetsEncrypt SSL certificate is only valid for 90 days. If it is not updated, it will cause errors. Are you worried about the certificate expiration issue? Although the free service of “LetsMonitor” can monitor whether the SSL encryption certificate of the website has expired, but if you want to send an email notification reminder before expiration, you must register an account, so you should register obediently.
After registration, you must also create regulations for monitoring the website on the Create “Monitors” page.
LetsMonitor can monitor many services, such as websites, SSL, performance, domain blacklists, domain name servers, etc. However, currently only SSL certificate monitoring is free.
Specify the name of the monitoring regulations, the website to be monitored, the notification time (default is seven days), etc., and click [OK] to generate the monitoring regulations.
After creating the rule, it is enabled by default. Click [Run Test] to take a look.
