In this commit, we create a new struct that houses the key derivation, address management, and account management for a particular scope. A scope consists of a (purpose, cointype) tuple. Additionally, each ScopedKeyManager is able to generate internal/external addresses for a specific *address type*. This make rescans easier as for each scope, we know what type of output to look for within the chain. The ScopedKeyManagers have two new primary methods that weren’t previously present within the regular Manager: * DeriveFromKeyPath * NewRawAccount These two methods allow callers a greater degree of control over the way that accounted are created and addressed derived. |

Package waddrmgr provides a secure hierarchical deterministic wallet address manager.
A 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. Package waddrmgr is licensed under the liberal ISC license.
Feature Overview
- BIP0032 hierarchical deterministic keys
- BIP0043/BIP0044 multi-account hierarchy
- Strong focus on security:
- Fully encrypted database including public information such as addresses as well as private information such as private keys and scripts needed to redeem pay-to-script-hash transactions
- Hardened against memory scraping through the use of actively clearing private material from memory when locked
- Different crypto keys used for public, private, and script data
- Ability for different passphrases for public and private data
- Scrypt-based key derivation
- NaCl-based secretbox cryptography (XSalsa20 and Poly1305)
- Scalable design:
- Multi-tier key design to allow instant password changes regardless of the number of addresses stored
- Import WIF keys
- Import pay-to-script-hash scripts for things such as multi-signature transactions
- Ability to export a watching-only version which does not contain any private key material
- Programmatically detectable errors, including encapsulation of errors from packages it relies on
- Address synchronization capabilities
- Comprehensive test coverage
