About this project

At some point I've wondered if there isn't a easier solution for verifying an app's signature.
Current solutions are not how I imagined the process to be, so I've developed this app.
Hope you like it. :)

Signature extraction inspired by MuntashirAkon/AppManager 💛

Features

• ✔️ Verification of app signatures via hash or hashfile
• 📲 Signature information of installed apps
• 📂 Signature information of APK files
• 🔒 private, no ads, no internet connection
• 💯 modern Material 3 design elements

Download

Google Play link coming soon

F-Droid link coming soon

Verification

The APK files can be verified using apksigner.

apksigner verify --print-certs -v example.apk

---

F-Droid and GitHub (signed using the same key)
The output should look like this:

Verifies
Verified using v1 scheme (JAR signing): true
Verified using v2 scheme (APK Signature Scheme v2): true

The certificate content and digests should look like this:

DN: OU=QuickTrust, O=Cyb3rKo OpenSource, L=GitHub / F-Droid, C=DE
Certificate Digests:
  SHA-256: c6:1d:51:8b:eb:a7:c0:e7:fb:68:59:e0:6b:05:e0:7b:aa:05:a3:88:86:7c:8e:95:ee:f4:fc:bf:02:c6:74:c3
  SHA-1:   6a:62:b2:a5:af:50:85:2c:2b:f3:e3:a0:5c:81:7c:f7:dd:e3:72:32
  MD5:     0d:94:e9:b8:60:23:2b:49:62:5e:2a:8b:fc:0d:da:db

Contribute

Of course I'm happy about any kind of contribution.

For creating issues there's no real guideline you should follow. If you create pull requests please try to use the syntax I use. Using a unified code format makes it much easier for me and for everyone else.
