Cryptography Lab
Elliptic Curve Cryptography Playground
Interactive sandbox for small prime fields. See the points, double-and-add steps and orders. For learning only lah—don't use with real secrets.
Elliptic-curve cryptography is the backbone of many crypto wallets and blockchains (e.g., secp256k1 in Bitcoin/Ethereum, Ed25519 in Solana/Ton). This demo use tiny primes so you can see the math; real production chains use big, audited curves and constant-time libraries for proper security.

⚠️ For learning only. Not secure, not constant‑time. For production use trusted libraries with safe curves (P‑256, Curve25519, Ed25519).
