Text to hash

Hashes

Click a hash to copy it. For passwords use a slow hash like bcrypt on your server, not plain SHA.

Create secure checksums in your browser – nothing is sent to a server.

What is the Hash Generator?

A hash is a fixed-length fingerprint of your data. Change one letter and the hash changes completely. This tool creates SHA-1, SHA-256, SHA-384 and SHA-512 hashes of any text right inside your browser using the Web Crypto API.

How to use the Hash Generator

  1. Type or paste your text.
  2. All hashes update instantly.
  3. Click a hash to copy it.

Frequently asked questions

Can a hash be reversed?

No. Hashes are one-way. You can only check if some text produces the same hash.

Is SHA-1 still safe?

SHA-1 is no longer considered secure for signatures. Use SHA-256 or higher.

This hash generator is 100% free, needs no signup and runs in your browser, so your data stays private.
