Cloudflare Workers Adds Support for Post-Quantum Cryptographic Algorithms

Today, Cloudflare Workers is adding support for post-quantum-resistant algorithms within Web Crypto.

For developers preparing for the post-quantum transition, these opt-in Web Crypto APIs make it easier to experiment with ML-KEM and ML-DSA without bundling a separate cryptographic implementation.

Neither option is ideal. They put the burden of selecting and maintaining cryptographic implementations on implementers, who see their applications get larger as they bundle cryptographic code. And this is work that needs to be reproduced for all downstream libraries. As the eco…
