Log Message:
-----------
Implement hdkeychain BIP0032 API.
This commit adds a new sub-package named hdkeychain which can be used to
derive hierarchical deterministic key chains which form the foundation of
hd wallets.
- Support for private and public extended keys
- Convenient cryptographically secure seed generation
- Simple creation of master nodes
- Support for multi-layer derivation
- Easy serialization and deserialization for both private and public
extended keys
- Support for custom networks by registering them with btcnet
- Obtaining the underlying EC pubkeys, EC privkeys, and associated bitcoin
addresses
ties in seamlessly with existing btcec and btcutil types which provide
powerful tools for working with them to do things like sign transactions
and generate payment scripts
- Makes use of the btcec package which is highly optimized for secp256k1
- Code examples including:
- Generating a cryptographically secure random seed and deriving a
master node from it
- Default HD wallet layout as described by BIP0032
- Audits use case as described by BIP0032
- Comprehensive test coverage including the BIP0032 test vectors
- Benchmarks
