If you have a personal or small business website that you wish to secure via an SSL/TLS certificate, you can use Let’s Encrypt to do it for free.
It used to be when you needed web encryption for your website, you had to go to a certificate authority and pay for one. What is worse, the certificate would have to be renewed every so often. It depends on how many years you paid for in advance.
If you opted not to renew your certificate, your web visitors would see a scary message telling them “Your connection to the website is not secure!”.
Technically the “your connection is not secure” message is incorrect. An expired certificate can still secure your connection to a server, assuming you have not enabled HSTS for your domain. It’s only that the web browser – and other software – will no longer “trust” the certificate because it has expired.
Some services give their users a user-friendly option to setup a Let’s Encrypt certificate for their website. However, for people like me with custom setups, we must use other less user-friendly solutions.
