KeyStoreViewer: App Signatures

Find the signing information you need for Android apps.

KeyStoreViewer helps developers inspect signing certificates from installed apps and APK files. View MD5, SHA-1, and SHA-256 certificate fingerprints and public key information without digging through command-line output.

KEY FEATURES

• Inspect the signing information of installed apps.

• Open an APK file to view its signing certificates.

• View MD5, SHA-1, and SHA-256 certificate fingerprints.

• View public key information, including the modulus for RSA keys.

• Copy fingerprints and public key values, or share signature details.

BUILT FOR EVERYDAY DEVELOPMENT

• Find the certificate fingerprints required by APIs and third-party SDKs.

• Retrieve signature and public key information for app registration.

• Investigate signing differences between debug and release builds.

Certificate fingerprints identify signing certificates. They are not APK file checksums, and a matching signature alone does not guarantee that an app is safe.
