# Validity90
This project aims on reverse engineering protocol of Validity 138a:0090, 138a:0094, 138a:0097, 06cb:0081, 06cb:009a fingerprint readers, creating specification and FLOSS libfprint driver.

## Notable files
1. [spec.md](spec.md) - Specification draft, the main work goes here right now.
2. [dissector.lua](dissector.lua) - Wireshark dissector for decrypting communication after key exchange.
3. ~[libfprint directory](libfprint) - libfprint repo with this driver integrated~ Not ready at the moment.
4. [prototype](prototype) - Standalone prototype(extremly ugly code, would be completly rewritten for driver)
## Testing
[Prototype](prototype) testers are needed, please share your result and join us in our [Gitter](https://gitter.im/Validity90/Lobby?utm_source=share-link&utm_medium=link&utm_campaign=share-link).
## Status
| Device | Status |
|-----------|--------|
| 138a:0090 | Scan, Image output, Internal DB check works in prototype. There is also a match-on-host [libfprint driver](https://github.com/3v1n0/libfprint) by @3v1n0 based on prototype source(138a:0090 only). You can use it untill proper unified driver is available. |
| 138a:0097 | Scan, Internal DB check works in prototype |
| 138a:0094 | Doesn't work yet, but looks promising. I will try to work on it after 90/97 |
| 06cb:0081 | So far looks identical to 138a:0094 |
| 06cb:009a | Init works, leds work, scan doesn't work yet |
| 138a:0091 | Different protocol, out of scope for this project. Check out [Validity91](https://github.com/hmaarrfk/Validity91) which aims to reverse engineer it.|
