Support for modern cryptographic algorithms in Workers
TL;DR
Cloudflare Workers now supports post-quantum-resistant cryptographic algorithms, specifically ML-DSA signatures, enhancing security for developers. This allows experimentation with modern cryptography without needing separate implementations.
✦ Why It Matters
Start experimenting with post-quantum cryptography in your applications using Cloudflare Workers today.
Key Takeaways
- Experiment with ML-KEM and ML-DSA in your applications now.
- Use the webcrypto_modern_algorithms flag to enable new features.
- Leverage native Web Crypto support to avoid bundling cryptographic libraries.
- Test your integration with real protocol code to identify issues.
How It Works
The integration allows developers to generate keys and perform cryptographic operations using ML-KEM and ML-DSA directly in JavaScript. For example, ML-KEM enables encapsulating a shared secret using a public key, while ML-DSA allows for signing and verifying data, similar to existing algorithms like Ed25519.
