0x56erify File Managers app for Android description
0x56erify is a minimal, offline-first checksum verification tool for Android.
Pick a file with the system document picker, compute its SHA-256 or SHA-512 checksum, and compare it against a hash you paste in (for example, one published alongside a download) to confirm the file wasn't corrupted or tampered with.
Features:
- Pick any file using Android's built-in Storage Access Framework picker
- Compute SHA-256 or SHA-512 checksums
- Streamed hashing: large files are never fully loaded into memory
- Copy or share the computed hash
- Paste an expected hash and get a clear MATCH / MISMATCH result
- Case-insensitive, whitespace-tolerant hash comparison
Privacy and permissions:
- All processing happens entirely on-device
- No network access, no INTERNET permission, no analytics, no ads, no accounts
- No broad storage permissions - files are accessed only through the system picker for the duration of the operation
- No proprietary or Google Play Services / Firebase dependencies
