cb58ref 0.2.0

Reference implementation of CB58 encoding used by AVA

cb58ref

cb58ref is a reference implementation of the CB58 encoding used by AVA. CB58 is similar to the Base58Check encoding used in Bitcoin

• both can encode arbitrary an arbitrary byte sequence

• both use the same alphabet

• both append a 4 byte checksum

they differ in the following respects

• CB58 uses the final 4 bytes of SHA256(msg) as the checksum. Base58Check uses the first 4 bytes of SHA256(SHA256(msg)) as the checksum.

Usage

>>> import cb58ref
>>> cb58ref.cb58encode(b"Hello world"):
'32UWxgjUJd9s6Kyvxjj1u'
>>> cb58ref.cb58decode('32UWxgjUJd9s6Kyvxjj1u')
b"Hello world"

$ printf "Hello world" | python3 -m cb58ref
32UWxgjUJd9s6Kyvxjj1u

$ printf "32UWxgjUJd9s6Kyvxjj1u" | python3 -m cb58ref -d
Hello world

Installation

$ python3 -m pip install cb58ref
