Functions

func Bech32Decode

func Bech32Decode(bech string) (string, []byte, error)

Decode decodes a bech32 encoded string, returning the human-readable part and the data part excluding the checksum.

func Bech32Encode

func Bech32Encode(hrp string, data []byte) (string, error)

Encode encodes a byte slice into a bech32 string with the human-readable part hrb. Note that the bytes must each encode 5 bits (base32).

func ConvertBits

func ConvertBits(data []byte, fromBits, toBits uint8, pad bool) ([]byte, error)

ConvertBits converts a byte slice where each byte is encoding fromBits bits, to a byte slice where each byte is encoding toBits bits.

func CreateEmptyRawTransaction

func CreateEmptyRawTransaction(vins []Vin, vouts []Vout, timeRange uint64, isTestNet bool) (string, error)

func CreateMultiSig

func CreateMultiSig(required byte, pubkeys [][]byte, isTestNet bool) (string, string, error)

func InsertSignatureIntoEmptyTransaction

func InsertSignatureIntoEmptyTransaction(txHex string, txHashes []TxHash) (string, error)

func VerifyRawTransaction

func VerifyRawTransaction(txHex string) bool
