HD 钱包比特币扩展。

此 crate 扩展了 hdwallet crate，根据 BIP-32 提供比特币密钥派生和序列化。查看 hdwallet 文档 了解如何派生 HD 密钥。查看 secp256k1 文档 了解如何签名。

示例

use hdwallet::{KeyChain, DefaultKeyChain, ExtendedPrivKey, traits::Serialize};
use hdwallet_bitcoin::{PrivKey as BitcoinPrivKey, Network as BitcoinNetwork};

let mut rng = rand::thread_rng();
let master_key = ExtendedPrivKey::random(&mut rng).expect("master key");
let key_chain = DefaultKeyChain::new(master_key);
let (extended_key, derivation) = key_chain.derive_private_key("m/1H/0".into()).expect("derive ExtendedPrivKey");
let key = BitcoinPrivKey {
    network: BitcoinNetwork::MainNet,
    derivation,
    extended_key,
};
let serialized_key: String = key.serialize();
println!("derive m/1H/0 key: {}", serialized_key);
