Module aigc_keychain::extkey_bip32

Implementation of BIP32 hierarchical deterministic wallets, as defined at https://github.com/bitcoin/bips/blob/master/bip-0032.mediawiki Modified from above to integrate into aigc and allow for different hashing algorithms if desired

Structs

• BIP32AigcHasher
  Implementation of the above that uses the standard BIP32 Hash algorithms
• ChainCode
  A chain code
• ExtendedPrivKey
  Extended private key
• ExtendedPubKey
  Extended public key
• Fingerprint
  A fingerprint

Enums

• ChildNumber
  A child number for a derived key
• Error
  A BIP32 error

Traits

• BIP32Hasher
  Allow different implementations of hash functions used in BIP32 Derivations Aigc uses blake2 everywhere but the spec calls for SHA512/Ripemd160, so allow this in future and allow us to unit test against published BIP32 test vectors The function names refer to the place of the hash in the reference BIP32 spec, not what the actual implementation is
