## What it is
KeyDecoder is a Flutter mobile app that lets pentesters and security enthusiasts measure the bitting of a mechanical key from a photo, using OpenCV image processing. It is intended for legal security auditing and educational use only.

## Use cases
- decode a mechanical key from a picture
- measure key bitting with a smartphone
- duplicate keys for pentest demonstrations
- assess how easily my keys can be copied from photos
- physical security audit tool for locksmith demonstrations

## When to choose
- you are a pentester demonstrating key-duplication risks to clients
- you are a security enthusiast assessing your own key security
- you need a mobile OpenCV-based key measurement tool

## When to avoid
- you want to duplicate keys without the owner's consent - this is illegal
- you need a general-purpose locksmith or key-cutting CAD tool
- you need a maintained product with a standard license - the license is non-standard and releases are infrequent
