Crate rustywallet_hd 

rustywallet-hd

BIP32/BIP44 Hierarchical Deterministic wallet for cryptocurrency key derivation.

This crate provides functionality to:

• Create master keys from seeds
• Derive child keys using BIP32 derivation
• Support BIP44 standard paths
• Export/import extended keys (xprv/xpub)

Example

use rustywallet_hd::prelude::*;

// Create master key from seed (64 bytes, typically from mnemonic)
let seed = [0u8; 64];
let master = ExtendedPrivateKey::from_seed(&seed, Network::Mainnet).unwrap();

// Derive BIP44 Bitcoin path: m/44'/0'/0'/0/0
let path = DerivationPath::bip44_bitcoin(0, 0, 0);
let child = master.derive_path(&path).unwrap();

// Get keys
let private_key = child.private_key().unwrap();
let public_key = child.public_key();

// Export as xprv/xpub
let xprv = child.to_xprv();
let xpub = child.extended_public_key().to_xpub();

BIP44 Paths

m / purpose' / coin_type' / account' / change / address_index

Bitcoin:  m/44'/0'/0'/0/0
Ethereum: m/44'/60'/0'/0/0

Security

• Private keys and chain codes are zeroized on drop
• Debug output masks sensitive data
• Hardened derivation prevents public key derivation
