Let’s Encrypt Passes 20 Million Active Certificates in 2016

Let’s Encrypt has just closed out its first full year as a certificate authority with more than 20 million active certificates. The free and open certificate authority focuses on lowering the complexity of setting up TLS encryption by making the process more automated. It came out of beta in April 2016 and the number of certificates issued per day has grown steadily since then. “At the start of 2016, Let’s Encrypt certificates had been available to the public for less than a month and we were supporting approximately 240,000 active (unexpired) certificates,” said Josh Aas, Executive Director of the non-profit Internet Security Research Group (ISRG). “Now we’re frequently issuing that many new certificates in a single day while supporting more than 20,000,000 active certificates in total. We’ve issued more than a million certificates in a single day a few times recently.”
Let’s Encrypt operates as a 501(c)(3) nonprofit and has received more than three dozen corporate sponsorships and grants, but funds for the coming year have fallen short. In November, Let’s Encrypt launched a crowdfunding campaign to cover the cost of one month
