candidateblock_bitcoin_library.base58 module

Base58 encoding.

Base58 and Base58Check encoding and decodings that are compatible with the bitcoin network.

class candidateblock_bitcoin_library.base58.Base58

Bases: object

classmethod check_decode(b58: str = '') → tuple

_summary_

Parameters:

b58 (str) – Base58Check encoded string

Raises:

ValueError – Checksum not valid

Returns:

A tuple containing, respectively, a bytes (address prefix) and a bytes (payload) and a bytes (checksum)

classmethod check_encode(payload: bytes = b'') → str

Encode a hex string using Base58Check

Base58Check 1. Takes input bytes payload 2. Computes the double-SHA256 checksum (4-Byte) and appends to end 3. Base58 encodes result

Parameters:

payload (bytes) – value in bytes

Returns:

Base58Check encoded paload & (4-Byte) checksum

Return type:

str

classmethod decode(b58: str = '') → bytes

Decode the Base58 encoded string

Check base58 string is valid, remove padding. A ValueError is raised if base58 has invalid chars Decode Base58 into bytes, even char pad with ‘0’ and with any leading ‘00’

Parameters:

b58 (str) – Base58 encoded string

Raises:

• ValueError – Input string can not be empty

• ValueError – string argument should contain only Base58 characters

Returns:

value in bytes

Return type:

bytes

classmethod encode(input: bytes = b'') → str

Encode bytes into a string using Base58

Take the input bytes and convert to Base58 using the Bitcoin alphabet, including leading 0x00’s coverted to ‘1’s

Parameters:

input (bytes) – value in bytes

Returns:

Base58 encoded

Return type:

str
