[−][src]Crate hdwallet

HD wallet(BIP-32) related key derivation utilities.

This crate is build upon secp256k1 crate, only provide BIP-32 related features, for signatures see the original secp256k1 documentation.

  • ChainPath and KeyChain used to derivation child keys from string represented path.
  • HDKey return value of key_chain.fetch_key, HDKey represent a derivated key which include a ExtendedPrivKey and other derivation info.
  • ExtendedPrivKey and ExtendedPubKey as BIP-32 described it is basic struct in hdwallet.
  • KeyIndex is a simple enum indicate the index and type of child key(Normal key or Hardened key).
  • Error errors.

Structs

ChainPath

ChainPath is used to describe BIP-32 KeyChain path.

ChildPrivKey

ChildPrivKey, derive from ExtendedPrivKey

ChildPubKey

ChildPubKey derive from ExtendedPubKey, or from ChildPrivKey

DefaultKeyChain
ExtendedPrivKey

ExtendedPrivKey is used for child key derivation. See secp256k1 crate documentation for SecretKey signatures usage.

ExtendedPubKey

ExtendedPubKey is used for public child key derivation. See secp256k1 crate documentation for PublicKey signatures usage.
