Watch-only accounts are usually backed by an external signer as they do not contain any private key information. Some external signers require a root key fingerprint for identification and signing purposes. In order to guarantee compatibility with external signers, we need to persist the root key fingerprint within the database. Before this change, watch-only accounts used the default account database structure. In this commit, we introduce a new account type to store different information for watch-only accounts only. This isn't a breaking change as watch-only accounts have yet to be supported by the primary user of the wallet (lnd). With this new account type, we can avoid the empty private key fields, which are irrelevant to watch-only accounts, and we can store the root key fingerprint. |

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 start in watching-only mode which does not contain any private key material
- Ability to convert to watching-only mode
- Programmatically detectable errors, including encapsulation of errors from packages it relies on
- Address synchronization capabilities
- Comprehensive test coverage
