#HDKey

The HDKey class provides methods to make derivation of hierarchical deterministic keys easier. This class is similar to the BIP32 class but provides some convenience methods for working with xpub and xprv values.

#Importing the HDKey class

1import { HDKey } from "@ardenthq/sdk-cryptography";

#Derive a key from a seed

1HDKey.fromSeed('a0c42a9c3ac6abf2ba6a9946ae83af18f51bf1c9fa7dacc4c92513cc4dd015834341c775dcd4c0fac73547c5662d81a9e9361a0aac604a73a321bd9103bce8af');

#Derive a key from an extended public key

1HDKey.fromExtendedPublicKey('xpub6FnCn6nSzZAw5Tw7cgR9bi15UV96gLZhjDstkXXxvCLsUXBGXPdSnLFbdpq8p9HmGsApME5hQTZ3emM2rnY5agb9rXpVGyy3bdW6EEgAtqt');

#Derive a key from an extended private key

1HDKey.fromExtendedPrivateKey('xprvA2nrNbFZABcdryreWet9Ea4LvTJcGsqrMzxHx98MMrotbir7yrKCEXw7nadnHM8Dq38EGfSh6dqA9QWTyefMLEcBYJUuekgW4BYPJcr9E7j');

#Derive a key from a compressed public key

1HDKey.fromCompressedPublicKey('fffcf9f6f3f0edeae7e4e1dedbd8d5d2cfccc9c6c3c0bdbab7b4b1aeaba8a5a29f9c999693908d8a8784817e7b7875726f6c696663605d5a5754514e4b484542');
