hdkeychain

Package hdkeychain provides an API for kaspa hierarchical deterministic extended keys.

Feature Overview

• Full BIP0032-compatible 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 dagconfig
• Obtaining the underlying EC pubkeys, EC privkeys, and associated kaspa addresses ties in seamlessly with existing ecc and util types which provide powerful tools for working with them to do things like sign transations and generate payment scripts
• Uses the ecc 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

Examples

• NewMaster Example Demonstrates how to generate a cryptographically random seed then use it to create a new master node (extended key).
• Default Wallet Layout Example Demonstrates the default hierarchical deterministic wallet layout as described in BIP0032.
• Audits Use Case Example Demonstrates the audits use case in BIP0032.
