eBase32

eBase32 is a custom Base32 encoding standard designed to be fully URL-safe and free from ambiguous characters. The goal is to provide a human-friendly, robust, and deterministic alternative to classical Base32 schemes such as Crockford or RFC 4648.

Features

• ✅ No ambiguous characters (0, O, I, l, 1, S, B, Z, etc.)
• ✅ Fully alphanumeric – no symbols
• ✅ Ideal for IDs, tokens, URLs, QR codes, or human-readable values
• ✅ No padding, no special rules

The character set consists of the following 32 characters:

ACEFHKLMNPRTWXYadeghknrtwxy34679

Installation

pip install eBase32

Usage

Functional API

from eBase32 import encode, decode

data = b"hello world"
encoded = encode(data)
decoded = decode(encoded)

assert decoded == data

Object-Oriented API

from eBase32 import EBase32

id = EBase32(b"hello")
print(str(id))         # eBase32 string
print(id.bytes)        # original bytes
print(id.string)       # eBase32 string (same as str())
print(bytes(id))       # original bytes

Comparison & Equality

a = EBase32(b"data")
b = EBase32(str(a))

assert a == b
assert a == b.bytes
assert a == b.string
