About XAPK Signature Checker
The XAPK Signature Checker Online is a powerful, client-side tool designed to help developers and Android users verify the integrity of their application packages. Whether you have a standard APK file or a compressed XAPK bundle, this tool extracts the digital signature (certificate) used to sign the app and calculates its unique fingerprints (MD5, SHA-1, and SHA-256).
Why Check APK Signatures?
- Security Verification: Ensure the app hasn't been tampered with or modified by third parties.
- Developer Identity: Confirm that the app was signed by the original developer (e.g., verifying the certificate subject).
- Safe Installation: When downloading apps from third-party stores like APKPure, Aptoide, or APKMirror, comparing the signature hash against the official one helps prevent malware infection.
How to Use
- Upload File: Drag and drop your .xapk or .apk file into the box above.
- Wait for Analysis: The tool will extract the internal APK and read the signing certificate. This happens entirely in your browser—no files are uploaded to a server.
- View Results: Instantly see the MD5, SHA-1, and SHA-256 hashes.
- Verify: Paste a known good hash into the "Verify Hash Match" box to confirm authenticity.
Frequently Asked Questions (FAQ)
What is an XAPK file? +
An XAPK file is a zip archive used to distribute Android apps. It typically contains the main APK file, an OBB file (for graphics/media), and a manifest.json. Standard Android installers cannot open XAPK files directly; they need a specialized installer or need to be extracted first.
Is this tool safe? +
Yes, absolutely. This tool runs 100% in your web browser using JavaScript. Your files are never uploaded to any server, ensuring your privacy and data security.
Can I check OBB files? +
This tool focuses on the cryptographic signature of the application executable (APK). OBB files are data assets and are not typically digitally signed in the same way as the APK itself.
