quantum website certificates from Cloudflare are scheduled for early 2027
Cloudflare plans to launch a public certificate authority in early 2027 that will support both standard and post-quantum Merkle Tree Certificates. This initiative aims to secure web traffic against future quantum computing threats while maintaining compatibility with older devices.
Why it matters
As quantum computing advances, current encryption standards face obsolescence; this move is a critical step in future-proofing internet security infrastructure.
Post-quantum website certificates from Cloudflare are scheduled for early 2027 Cloudflare plans to become a public certificate authority (CA), an organization that issues the digital certificates websites use to encrypt traffic and prove who they are. The company said that its CA will issue conventional certificates and a post-quantum type called Merkle Tree Certificates ( MTCs ), with production MTC issuance scheduled for the first quarter of 2027.
Cloudflare says much of the web’s certificate issuing rests on a small set of dominant CAs, so one failure or compromise would spread widely. It also expects quantum computers able to break today’s encryption within years . A new high-scale issuer is its answer to the first problem, and MTCs are its answer to the second.
