Functions

func ComputeMastersFromSeed

func ComputeMastersFromSeed(seed []byte) (secret [32]byte, chainCode [32]byte)

ComputeMastersFromSeed returns the master public key, master secret, and chain code in hex.

func DerivePrivateKeyForPath

func DerivePrivateKeyForPath(privKeyBytes [32]byte, chainCode [32]byte, path string) ([32]byte, error)

DerivePrivateKeyForPath derives the private key by following the BIP 32/44 path from privKeyBytes, using the given chainCode.
