KEMTLS: Post-quantum TLS without signatures

What this post added

This post introduces KEMTLS, a novel mechanism for achieving post-quantum TLS without relying on traditional signatures. It addresses the challenge of larger post-quantum cryptographic primitives by replacing handshake signatures with key encapsulation mechanisms (KEMs), significantly reducing handshake data size and improving efficiency. Cloudflare has implemented this in Golang's TLS 1.3 suite, demonstrating a commitment to future-proofing internet security against quantum computing threats.
