This updates all code in the main package and subpackages to make use of the new chainhash package since the old wire.ShaHash type and functions have been removed in favor of the abstracted package. Also, since this required API changes anyways and the hash algorithm is no longer tied specifically to SHA, all other functions throughout the code base which had "Sha" in their name have been changed to Hash so they are not incorrectly implying the hash algorithm. The following is an overview of the changes: - Update all references to wire.ShaHash to the new chainhash.Hash type - Rename the following functions and update all references: - Block.Sha -> Hash - Block.TxSha -> TxHash - Tx.Sha -> Hash - bloom.Filter.AddShaHash -> AddHash - Rename all variables that included sha in their name to include hash instead - Add license headers to coinset package files |

Package hdkeychain provides an API for bitcoin hierarchical deterministic extended keys (BIP0032).
A comprehensive suite of tests is provided to ensure proper functionality. See
test_coverage.txt for the gocov coverage report. Alternatively, if you are
running a POSIX OS, you can run the cov_report.sh script for a real-time
report.
Feature Overview
- Full BIP0032 implementation
- Single type for private and public extended keys
- Convenient cryptograpically 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 chaincfg
- 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 transations and generate payment scripts
- Uses 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
