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.
libfrprint issue: https://gitlab.freedesktop.org/libfprint/libfprint/issues/54
- spec.md - Specification draft, the main work goes here right now.
- dissector.lua - Wireshark dissector for decrypting communication after key exchange.
libfprint directory - libfprint repo with this driver integratedNot ready at the moment.
- prototype - Standalone prototype(extremly ugly code, would be completly rewritten for driver)
|138a:0090||Scan, Image output, Internal DB check works in prototype. There is also a match-on-host libfprint driver 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 which aims to reverse engineer it.|
