public static class KeyDerivation.Bip32Node
Represents a node in the Bip32 derivation tree.
Use this node to:
Obtain the Curve25519 private/public key pair for signing and encryption
Derive child nodes with both private and public data
Derive child nodes with only public data
Given a master public key and chain code of a non-hardened parent node and any child private key, anyone can easily reproduce the parent node
private key and all child private keys. Therefore maintain the pair master public key + chain code private
