Let's Encrypt - an automated certification authority providing free SSL certificates for websites. The goal of this project is to increase the level of security of sites everywhere, since the HTTPS protocol allows the transfer of data from the client to the server in encrypted form, which makes it impossible for third parties to get this data.
Obtaining a certificate is fully automatic, but requires some basic knowledge of server administration. On our hosting installing a certificate is even more simplified and does not require any additional knowledge, you just need to submit a request to install a certificate.
In the process of installing the certificate, Let's Encrypt verifies and validates the domain name and site by sending a series of requests or using DNS-records. The process of issuing / revoking certificates is described in more detail at official website.
