File Hash Checksum Generator
- Browser-based
- No signup
This file hash checksum generator computes digests from uploaded files so you can verify downloads, detect tampering, and compare build artifacts. Select algorithm, hash locally in the browser, and match against published checksums.
Checksum verification confirms file integrity—not authenticity unless the checksum itself is signed or from a trusted channel.
Large files may take seconds to hash in the browser depending on device speed.
100% Client-Side
Your data never leaves your computer.
How to use this tool
Upload the file, pick hash algorithm, generate checksum, and compare hex output to the reference value character by character.
Worked example
Example: hash a downloaded `.iso` with SHA-256 and compare to the publisher checksum before creating a bootable USB drive.
When to use this
- Verifying open-source release downloads.
- Confirming backup archives copied without corruption.
- Comparing CI artifact hashes across environments.
Common examples
- GitHub release SHA-256 → hash the exact release tag string and compare against the checksum published on the release page (use File Checksum for the downloaded .zip).
- Webhook signing secret → SHA-256 of the shared secret for log correlation—not for password storage (use bcrypt or Argon2 in apps).
- Deployment config snippet → SHA-384 digest to confirm the same environment variable text across staging and production.
- Config string `prod-v2.3.1` → SHA-256 to compare with CI-published digest.
- License paragraph text → SHA-384 fingerprint for internal document registry.

How it works
Enter text and choose SHA-256, SHA-384, or SHA-512. Hashes are generated with the Web Crypto API in your browser.

Frequently asked questions
Which algorithm should I use?
Match the algorithm published by the file provider—often SHA-256 or SHA-512 today.
Are files uploaded to Utilnivo?
Standard hashing runs locally in your browser.
Hash mismatch after download?
Re-download from the official mirror— the file may be corrupted or tampered.
