Let’s Encrypt is a free certificate authority developed by the Internet Security Research Group (ISRG).
Let’s Encrypt provides two types of certificates. The standard single domain SSL and the Wildcard SSL, which covers not only a single domain, but all of its subdomains too. Both types of SSL certificates are issued for a period of 90 days, and on Eltris servers when installed they are renewed automatically. These certificates are domain-validated, don’t require a dedicated IP, and are supported on all Eltris hosting solutions.
