Really interesting development from CloudFlare on encrypting the webs connections. Takes their ‘Flexible SSL’ to the next level and beyond.
“Faster, more secure alternative to public CA certificates for your CloudFlare-fronted servers. Extraneous overhead removed to optimize performance.
With Origin CA, we questioned all aspects of certificate issuance and browser validation, from domain control validation (DCV) to path bundling and revocation checking. We asked ourselves what cruft public CAs would remove from certificates if they only needed to work with one browser, whose codebase they maintained? Questions such as “why bloat certificates with intermediate CAs when they only need to speak with our NGINX-based reverse proxy” and “why force customers to reconfigure their web or name server to pass DCV checks when they’ve already demonstrated control during zone onboarding?” helped shape our efforts.”
