Overview

Package bech32 provides a Go implementation of the bech32 format specified in BIP 173.

Bech32 strings consist of a human-readable part (hrp), followed by the separator 1, then a checksummed data part encoded using the 32 characters "qpzry9x8gf2tvdw0s3jn54khce6mua7l".

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.

Example

This example demonstrates how to decode a bech32 encoded string.

encoded := "bc1pw508d6qejxtdg4y5r3zarvary0c5xw7kw508d6qejxtdg4y5r3zarvary0c5xw7k7grplx"
hrp, decoded, err := Bech32Decode(encoded)
if err != nil {
	fmt.Println("Error:", err)
}

// Show the decoded data.
fmt.Println("Decoded human-readable part:", hrp)
fmt.Println("Decoded Data:", hex.EncodeToString(decoded))
Output:

Decoded human-readable part: bc
Decoded Data: 010e140f070d1a001912060b0d081504140311021d030c1d03040f1814060e1e160e140f070d1a001912060b0d081504140311021d030c1d03040f1814060e1e16

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.
