Let's Encrypt is a free, automated and open source Certificate Authority issuing digital certificates for website encryption globally. Let's Encrypt is a service provided by the Internet Security Research Group (ISRG), a public benefit organization with a mission to reduce financial, technological, and education barriers to secure communication over the Internet. Let's Encrypt serves Web users globally, issuing certificates in every country. Because it removes the barriers of payment and technical know-how, Let's Encrypt has significantly impacted the security and privacy of the Web by enabling HTTPS adoption. The organization's goal is to get the Web to 100% adoption of encryption via HTTPS (as of January 1, 2017, only 46% of all Web page loads were encrypted).
