Check Signature

Verify Android APK signing certificates and compare signer fingerprints with apksigner

jason0404 Updated

File contents

Verify signing for one or more .apk files.

Workflow

  1. Confirm supplied files exist and are APKs.
  2. Locate apksigner cross-platform through PATH or Android SDK build-tools locations.
  3. Invoke android-apk-signing-verifier.
  4. Use apksigner verify --print-certs when available.
  5. Report verification status, signer count and certificate SHA-256 digest where returned.
  6. When comparing APKs, state whether the confirmed certificate fingerprints match.
  7. Generate an HTML report only when requested.

Safety

Never request or expose keystore passwords or private signing material. Do not claim which Play Console key a certificate represents unless that evidence was separately provided.
