Cloudflare launches certificate authority for quantum-resistant web

Cloudflare just announced it's becoming a certificate authority (CA), with plans to issue a new type of post-quantum secure credential called Merkle Tree Certificates (MTCs). They're targeting early 2027 for MTC support in Chrome’s upcoming quantum-resistant root store. Standard MTC issuance will be free, making it easier for websites to upgrade before quantum computers threaten today's encryption.

Why it mattersQuantum computers could eventually break the encryption protecting most internet traffic. By pushing MTCs and supporting post-quantum standards, Cloudflare is aiming to keep web users safe as that risk gets closer.
