About the APK Certificate Inspector (SHA-1 / SHA-256)

Drop an Android .apk and read its signing certificate without installing keytool or apksigner. The tool finds v1 (JAR) signatures in META-INF and v2/v3 APK Signing Block certificates, then shows the subject, issuer, organization, serial number, validity dates, key algorithm and size, plus SHA-1, SHA-256 and MD5 fingerprints — exactly the values Google Play, Firebase, Google Maps and Facebook ask for. Export any certificate as PEM. Everything runs locally in your browser.
