About Checksum Verifier
Compute and verify checksums (such as MD5 and SHA-256) for files or text to confirm integrity. Compare a downloaded file’s hash against the publisher’s value to detect corruption or tampering.
How to use
- Select a file or paste text.
- Choose the hash algorithm (e.g. SHA-256).
- Compare the generated checksum against the expected value.
Frequently asked questions
- Does my file get uploaded?
- No — hashing runs in your browser via the Web Crypto API, so the file never leaves your device.
- Which algorithm should I use?
- Prefer SHA-256 for integrity checks; MD5 is offered for compatibility but is not collision-resistant.
