# ecc-secp256k1

## This repository is for learning purposes only, please *DO NOT* use in production

This repository aims to create a pure rust ECC library (in the end secp256k1 only).

right now it's *not* optimized, *not* constant time

It provides both low level API (Mul/Add/Div etc.), and Private/Public Keys interface with ECDSA, ECDH and Schnorr.

## TODO:

- [x] ECDSA

- [x] ECDH

- [x] Implement DER formats.

- [x] Test against a known secp256k1 library.

- [x] ~~Add NIST test vectors~~

- [x] Replace random `k` with deterministic(ECDSA).

- [ ] Remove the usage of GMP library.

- [x] Look into implementing sha2 myself.

- [ ] Remove all `unimplemented!()` and add checks for the points all over.

- [x] Add BIP Schnorr support. 

- [x] Add BIP Schnorr Test vectors.

- [ ] Implement MuSig.

- [ ] Bulletproofs?
