Algorithm utility

Checksum Lab

A command-line checksum utility for one's-complement addition across equal-width bit blocks. This is also the logic behind the checksum demo on the homepage.

Browser tie-in

Shared demo logic

The interactive checksum lab in the site mirrors the same idea used by the CLI utility.

Primary use

Algorithm verification

Useful when you want to validate checksum behavior independently of socket code.

Run locally

python projects/checksum-lab/cli.py 1010 0101 1111

Why it belongs in the site

It makes the browser demo feel grounded in actual project logic.
It provides a non-network entry point for understanding error-detection steps.
It closes the gap between the static site and the Python implementation.
