Cloudflare said Tuesday it plans to issue quantum-proof TLS certificates, making it one of the first authorities to issue such certificates, which use a form of cryptography that is widely believed to withstand attacks from quantum computers. The Internet infrastructure provider said it will use an open source platform that issues both classic TLS certificates and a post-quantum equivalent known as Merkle Tree Certificates. The hybrid certificates will be free to both paying and non-paying users. Ars Technica reported this update on 2026-09-30 with additional details in the linked source coverage.
5-Second Takeaway
Cloudflare said Tuesday it plans to issue quantum-proof TLS certificates, making it one of the first authorities to issue such certificates, which use a form of cryptography that is widely believed to withstand attacks from quantum computers.
Why This Matters
The Internet infrastructure provider said it will use an open source platform that issues both classic TLS certificates and a post-quantum equivalent known as Merkle Tree Certificates. The hybrid certificates will be free to both paying and non-paying users.
