Overview

Package encoding provides different encodings used in bitcoin and also utility functions that use this encodings.

Functions

func Address

func Address(pub *ecdsa.PublicKey, compressed, testnet bool) string

Address returns the associated bitcoin address in base58check for the public key as string.

func AddressToPubKeyHash

func AddressToPubKeyHash(s string) ([20]byte, error)

AddressToPubKeyHash recovers the public key hash from an address in base58check.

Returns error if the checksum doesn't match.

func DecodeVarInt

func DecodeVarInt(r io.Reader) *big.Int

func EncodeVarInt

func EncodeVarInt(i *big.Int) ([]byte, error)

func Wif

func Wif(priv *ecdsa.PrivateKey, compressed, testnet bool) string

Wif encodes the private key in WIF format.

WIF has the following format: [1 byte net id] [D in big-endian] [suffix if compressed] [4 bytes checksum]
