🔒 What is APK Signature Verification?
APK Signature Verification is a process used to confirm that an APK file has not been altered since it was signed by the original developer. It guarantees the file's authenticity and integrity, protecting users from modified or malicious apps.

Why Signature Verification Matters
- Prevents installation of tampered or fake apps.
