Types

type Key

type Key struct {
	// Version bytes.
	Version [4]byte
	// Depth, 0x00 for master nodes, 0x01 for level-1 derived keys, ...
	Depth [1]byte
	// Fingerprint of the parent's key (0x00000000 if master key).
	FingerPrint [4]byte
	// Child number (0x00000000 if master key).
	ChildNumber [4]byte
	// Chain code.
	ChainCode [32]byte
	// KeyData for the public/private key.
	PrivateKeyData [32]byte
	PublicKeyData  [33]byte

	IsPublic bool // Internal use.
}
