Functions

func Checksum

func Checksum(payload []byte) []byte

Bitcoin P2P packet checksum

func DecodeOnion

func DecodeOnion(addr []byte) (string, error)

Extract .onion from 16-byte "IPv6" address used by Bitcoin P2P

func EncodeOnion

func EncodeOnion(onion string) ([]byte, error)

Encode .onion address into 16-byte "IPv6" address used by Bitcoin P2P

func Hash256

func Hash256(payload []byte) [32]byte
