Let's Encrypt is a certificate authority that provides free X.509 certificates for TLS encryption.

Let's Encrypt is a certificate authority that entered public beta on December 3, 2015 that provides free X.509 certificates for Transport Layer Security encryption (TLS) via an automated process designed to eliminate the current complex process of manual creation, validation, signing, installation and renewal of certificates for secure websites.

An Python certificate management program called letsencrypt gets installed on the client side (the web server of an enrollee). This is used to order the certificate, to conduct the domain validation process, to install the certificate, to configure the HTTPS encryption in the HTTP server, and later to regularly renew the certificate.

After installation and agreeing to the user license, executing a single command is enough to get a valid certificate installed. Additional options like OCSP stapling or HTTP Strict Transport Security (HSTS) can also be enabled. Automatic setup initially only works with Apache and nginx.
