How to Use the Hash Verifier

1. Paste input and expected hash

The data plus the hash to check it against, same algorithm both sides.

2. Verify

Run verification and read match or mismatch.

3. Trust matches only

A match proves integrity; a mismatch means re-download from the source.

Frequently Asked Questions

Which algorithms?

SHA-1, SHA-256, and SHA-512 — pick one per verification run.

File or text?

Text mode only — paste the original text and the expected hash; there is no file-drop verification.

Timing attacks?

No — comparison is a plain string equality check, not constant-time. Fine for integrity checks, not for side-channel-sensitive secrets.

Is my input uploaded anywhere when using Hash Verifier?

No — verification runs locally in your browser; unlimited saves on local tools.
