KeyDecoder

KeyDecoder app lets you use your smartphone or tablet to decode your mechanical keys in seconds.

Just place it on a ISO card (loyalty card, transportation ticket, Hotel room RFID card...), take a picture, and place your features on the picture. In less than one minute, you can decode your key.

This application is a true key decoder for standard keys, giving you a precision of 0.1mm or less depending on the quality of your pictures, the lighting, angle of view, and of course the precision of the ISO sized card you will use as a dimensional reference.

If you want to decode a key, this key decoding app is the best way, and it's free!

It is published under the Aladdin Free Public License, making it source-available, free to use, modify and distribute. You can find it on github for all details.

The main intended use of this app is for Pentesters doing Physical Intrusion tests with a legal contract. If you want to avoid unwanted duplication of your keys, you should give them the same attention as passwords (which they are in a way), do not share them, do not leave them unattended.
