NBip32Fast
High perfomance and low allocation BIP-32 HD key derivation library for .NET 9+
Usage
Basic
var der = new Bip32Key();
Secp256K1HdKey.Instance.DerivePath("m/44'/0'/0'/0/0", seed, ref der);
NistP256HdKey.Instance.DerivePath("m/44'/0'/0'/0/0", seed, ref der);
Ed25519HdKey.Instance.DerivePath("m/44'/0'/0'/0'/0'", seed, ref der);
Extended (tree-like)
var master = new Bip32Key();
Ed25519HdKey.Instance.DerivePath("m/44'/888'/0'/0'", seed, ref master);
var accounts = new List<byte[]>();
var derResult = new Bip32Key();
for (var i = 0u; i < 5u; i++)
{
Ed25519HdKey.Instance.Derive(ref master, KeyPathElement.Hard(i), ref derResult);
accounts.Add(Ed25519HdKey.Instance.GetPublic(derResult.Key));
}
