Elliptic curve calculator just got a new big update: 1. Select a curve, including NIST, ed448, BLS 2. Create custom curves 3. Add and multiply points 4. Sign messages with different hashes The demo works offline. It’s great for learning! Check it out:

Paul Miller — Noble cryptography

Paul Miller. I make projects which help developers to build awesome things

4KB cryptography. Does that sound safe? Because it should. Announcing v2 of single-feature modules noble secp256k1 and noble ed25519. secp is just 430 lines of code (4KB gzipped), ed is only 330 lines (3.3KB gzipped) — 4x smaller than previous versions. Tweetnacl was a great idea. Smaller attack surface means less things that could go wrong. New libraries develop the concept further: there are tons of comments everywhere, describing how things work - makes it much easier for cryptography newcomers to read.
