Let's Encrypt shorter-lived certificates

The past year at ISRG has been a great one with Let’s Encrypt serving more websites worldwide than ever before. The introduction of shorter-lived certificates with a lifetime of six days is a major upgrade for TLS security, requiring the issuance of potentially 100,000,000 certificates per day in the future. The success of Let’s Encrypt and other projects is thanks to the support of donors and partners, shaping the future of internet security.
