A simple implementation of short authentication strings

Project description

Short authentication strings for Python

This package implements rendering of short authenticated strings, which you can use in your application after an unauthenticated exchange such as a Diffie-Hellman process.

The usual way in which this works is, both sides of the exchange display (hopefully) the same sequence based on the shared key (or a derivative of it), indicating that the shared key is, in fact, shared and has not been tampered with by an active man in the middle.

Here is a sample from a Python REPL:

>>> from shortauthstrings import emoji
>>> print(emoji(bytes([4,88,75,34,99,124])))
🍋 🍧 🍝 🌰 🍮 🦝

A ready-to-go module to perform Diffie-Hellman key agreement can be found in the blindecdh repository.

See module for more documentation.
