## What it is
An educational library collecting explanations and Python implementations of attacks on encryption systems, digital signatures, MACs, and authenticated encryption, supplemented with CTF challenges and write-ups. It serves as both a learning platform for offensive/defensive cryptography and a reference tool for solving CTF crypto challenges.

## Use cases
- learn cryptography attacks with worked examples
- practice CTF crypto challenges
- find write-ups for known cipher vulnerabilities
- reference implementations of padding oracle and other attacks
- prepare for capture the flag competitions
- study attacks on digital signatures and MACs

## When to choose
- you are a CTF player learning or practicing cryptography attacks
- you want explanations paired with runnable Python exploit code
- you need example challenges organized by attack type

## When to avoid
- you need production-grade cryptographic code - the author explicitly warns implementations are trivial and insecure
- you want a maintained library with recent updates - last release was 2021
- you need a general-purpose crypto library like PyCryptodome

## Facets
- artifact type: learning-resource
- maturity: maintenance
- function: cryptography, security, developer-tools
- domain: security, education
- platform: python, cross-platform
- tags: ctf, cryptanalysis, offensive-security, tutorials, writeups, cryptography
