bech32

Documentation

Overview

Package bech32 includes a Bech32 string which is at most 90 characters long and consists of: The human-readable part, which is intended to convey the type of data, or anything else that is relevant to the reader. This part MUST contain 1 to 83 US-ASCII characters, with each character having a value in the range [33-126]. HRP validity may be further restricted by specific applications.

The separator, which is always "1". In case "1" is allowed inside the human-readable part, the last one in the string is the separator.

The data part, which is at least 6 characters long and only consists of alphanumeric characters excluding "1", "b", "i", and "o".

Functions

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 Decode

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

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

func Encode

func Encode(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).
