High perfomance BIP-32 HD key derivation library for .NET 8

Usage

Basic

var secp256k1Key = Secp256K1.Secp256K1HdKey.Instance.DerivePath("m/44'/0'/0'/0/0", seed).Key;
var nistP256Key = NistP256.NistP256HdKey.Instance.DerivePath("m/44'/0'/0'/0/0", seed).Key;
var ed25519Key = Ed25519.Ed25519HdKey.Instance.DerivePath("m/44'/0'/0'/0'/0'", seed).Key;

Optimised

var master = Ed25519.Ed25519HdKey.Instance.DerivePath("m/44'/888'/0'/0'", seed);
var accounts = new List<byte[]>();

for (var i = 0u; i < 5u; i++)
{
    accounts.Add(Ed25519.Ed25519HdKey.Instance.GetPublic(Ed25519.Ed25519HdKey.Instance.Derive(master, new KeyPathElement(i, true)).Key));
}

TODOs

  • Ed25519 soft derivation scheme (used in Cardano)
  • KeyPathTree for efficient computing (for multiple keypath merging and index depth)
  • HDKey refactoring with public key lazy addition
  • More testing
