z-base-32: human-oriented base-32 encoding

z-base-32

The z-base-32 is a human oriented base32 encoding.

API

The library exposes two functions with following signatures and error type:

pub fn encode(input: &[u8]) -> String;

pub fn decode(input: &str) -> Result<Vec<u8>, DecodeError>;

pub struct DecodeError;

Example

use zbase32::{encode, decode};

fn main() {
    assert_eq!(encode(b"foo"), "c3zs6".to_string());
    assert_eq!(Ok(b"foo"), decode("c3zs6".to_string()));
    assert_eq!(decode(&encode(b"foo")).unwrap(), b"foo")
}

Python

Building

This crate can be compiled with feature flag python in which case it produces Python bindings. To build a Python wheels use maturin:

maturin build

API

def encode(input: bytes) -> str:

def decode(input: str) -> bytes:

class DecodeError(Exception):

Example

import zbase32

assert zbase32.encode(b'foo') == 'c3zs6'

assert zbase32.decode('c3zs6') == b'foo'


try:
    zbase32.decode('invalid@char')
except zbase32.DecodeError as e:
    print(e)
