About this tool

Hash Generator creates SHA-1/SHA-256 fingerprints for integrity checks.

Compare SHA-256 fingerprints to verify downloads match. Do not store passwords with this raw hash—use a salted KDF on the server.

Tip — Do not store passwords with a bare hash — use salted, stretched algorithms.

How to use

  1. 1Choose an algorithm (for example SHA-256).
  2. 2Enter your text.
  3. 3Copy the hash shown automatically.

FAQ

Which algorithm?

SHA-256 is a solid default for integrity. SHA-1 is legacy-only, not for security.

Same input, different hash?

Check trailing spaces, newlines, and selected algorithm.

Hash files?

If the tool is text-only, paste text or use a dedicated file checksum utility.

Are files uploaded to a server?

No. Every tool runs entirely in your browser. Files and text you enter are never sent to our servers.
