bech32_base

Module for base bech32 decoding/encoding.

class Bech32BaseConst

Bases: object

Class container for Bech32 constants.

CHARSET: str = 'qpzry9x8gf2tvdw0s3jn54khce6mua7l'

static ConvertToBase32(data: Union[List[int], bytes]) → List[int]

Convert data to base32.

Parameters:

data (list[int] or bytes) – Data to be converted

Returns:

Converted data

Return type:

list[int]

Raises:

ValueError – If the string is not valid

static ConvertFromBase32(data: Union[List[int], bytes]) → List[int]

Convert data from base32.

Parameters:

data (list[int] or bytes) – Data to be converted

Returns:

Converted data

Return type:

list[int]

Raises:

ValueError – If the string is not valid

static ConvertBits(data: Union[bytes, List[int]], from_bits: int, to_bits: int, pad: bool = True) → Optional[List[int]]

Perform bit conversion. The function takes the input data (list of integers or byte sequence) and convert every value from the specified number of bits to the specified one. It returns a list of integer where every number is less than 2^to_bits.

Parameters:

• data (list[int] or bytes) – Data to be converted

• from_bits (int) – Number of bits to start from

• to_bits (int) – Number of bits to end with

• pad (bool, optional) – True if data must be padded with zeros, false otherwise

Returns:

List of converted values, None in case of errors

Return type:

list[int]
