In this commit, we add a new migration to the waddrmgr to populate the birthday block for existing wallets. This will deem useful when performing rescans for whatever reason, as we'll now be able to start from this point rather than the genesis block, incurring a longer rescan. The migration is not as reliable since we do not store block timestamps, so we'll need to estimate our height by looking at the genesis timestamp and assuming a block occurs every 10 minutes. This can be unsafe, and cause us to actually miss on-chain events, so a sanity check will be added before the wallet attempts to sync itself in a later commit. |

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
