Research direction

The issue asks to publish the APK signing certificate fingerprint. First, generate the SHA-256 fingerprint of the app's signing certificate using keytool -printcert -jarfile app.apk. Then, add this fingerprint to the project's README.md file and/or the GitHub Releases page notes. Verify the change by checking the updated documentation in the repository.

Description

Use case

I'm installing this app via Obtanium / sideloading, and I'd like to make sure the APK I install is genuinely signed by you (and not a tampered or repackaged build).

To verify this, I use a certificate-fingerprint check (e.g., AppVerifier, or keytool -printcert -jarfile app.apk on desktop). For that to work, I need the signing certificate's fingerprint published somewhere I can compare against.

Proposed solution

Please add the SHA-256 fingerprint of the signing certificate (SHA-1 is a fine bonus) to the README and/or the Releases page, e.g.:
