Hash & checksum guide
Use this tool to verify file integrity or compare text fingerprints during delivery, backup, or release processes.
Verification flow
- Hash the original file and save the digest separately.
- After transfer, hash the received file with the same algorithm.
- Treat any mismatch as potential corruption or tampering.
Algorithm notes
- Prefer SHA-256 for modern integrity checks.
- Use MD5/SHA-1 only for legacy compatibility scenarios.
- Always compare full digest strings, not short fragments.
