Let’s Encrypt is a free, automated, and open certificate authority (CA), run for the public’s benefit. It is a service provided by the Internet Security Research Group (ISRG).
Let’s Encrypt give people the digital certificates they need in order to enable HTTPS (SSL/TLS) for websites, for free, in the most user-friendly way we can. Let’s Encrypt can do this because they want to create a more secure and privacy-respecting Web.
The key principles behind Let’s Encrypt are
Free: Anyone who owns a domain name can use Let’s Encrypt to obtain a trusted certificate at zero cost.
Automatic: Software running on a web server can interact with Let’s Encrypt to painlessly obtain a certificate, securely config- ure it for use, and automatically take care of renewal.
Secure: Let’s Encrypt will serve as a platform for advancing TLS security best practices, both on the CA side and by helping site operators properly secure their servers.
Transparent: All certificates issued or revoked will be publicly recorded and available for anyone to inspect.
To enable HTTPS on your website, you need to get a certificate (a type of file) from a Certificate Authority (CA). Let’s Encrypt is a CA. In order to get a certificate for your website’s domain from Let’s Encrypt, you have to demonstrate control over the domain. With Let’s Encrypt, you do this using software that uses the ACME protocol, which typically runs on your web host.
To figure out what method will work best for you, you will need to know whether you have shell access (also known as SSH access) to your web host. If you manage your website entirely through a control panel like cPanel, Plesk, or WordPress, there’s a good chance you don’t have shell access. You can ask your hosting provider to be sure.
With Shell Access We recommend that most people with shell access use the Certbot ACME client. It can automate certificate issuance and installa- tion with no downtime. It also has expert modes for people who don’t want autoconfiguration. It’s easy to use, works on many operating systems, and has great documentation. Visit the Certbot site to get customized instructions for your operating system and web server.
If Certbot does not meet your needs, or you’d like to try something else, there are many more ACME clients to choose from. Once you’ve chosen ACME client software, see the documentation for that client to proceed.
If you’re experimenting with different ACME clients, use our staging environment to avoid hitting rate limits.
Without Shell Access The best way to use Let’s Encrypt without shell access is by using built-in support from your hosting provider. If your hosting pro- vider offers Let’s Encrypt support, they can request a free certificate on your behalf, install it, and keep it up-to-date automatically. For some hosting providers, this is a configuration setting you need to turn on. Other providers automatically request and install certificates for all their customers.
Check our list of hosting providers to see if yours is on it. If so, follow their documentation to set up your Let’s Encrypt certificate.
