Functions

func BoolToString

func BoolToString(input bool) string

BoolToString converts bool to int represented in string

func BuildSecret

func BuildSecret(privateKey *btcec.PrivateKey, walletID, coin, netShort string) (string, error)

BuildSecret derives invitation secret for multi-signature wallets

func Hash160

func Hash160(data []byte) ([]byte, error)

Hash160 performs the same operations as OP_HASH160 in Bitcoin Script It hashes the given data first with SHA256, then RIPEMD160

func HashMessage

func HashMessage(input []byte) []byte

HashMessage calculates double sha-256 and returns reverse bytes

func ParseSecret

func ParseSecret(secret string) (*btcec.PrivateKey, string, string, string, error)

ParseSecret parses shared wallet secret

func Reverse

func Reverse(data []byte) []byte

Reverse reverses byte array

func Sha256

func Sha256(data []byte) []byte

Sha256 calculates sha-256 sum

func SignMessage

func SignMessage(data []byte, privateKey *btcec.PrivateKey) ([]byte, error)

SignMessage takes message hash and generates ECDSA signature with private key

func ToBytes

func ToBytes(input string) ([]byte, error)

ToBytes converts hex-encoded string to bytes

func ToHex

func ToHex(input []byte) string

ToHex converts bytes to hex-encoded string

func VerifyMessage

func VerifyMessage(data, sig []byte, publicKey *btcec.PublicKey) (bool, error)

VerifyMessage takes message hash and verifies it's signature using public key
