SHA-256 Hash Generator Developer
Produce a SHA-256 hash of any text using the browser’s own crypto.
SHA-256 Hash Generator is a free online tool that produce a SHA-256 hash of any text using the browser’s own crypto. It runs entirely in your web browser using WebCrypto, so files are processed on your own device and never uploaded to a server. There is no sign-up, no file size limit imposed by the site, no watermark and no paid tier.

About SHA-256 Hash Generator
SHA-256 is part of the SHA-2 family published by NIST in 2001 and remains unbroken — no collision has ever been found, and none is expected. It produces a 256-bit digest, shown as 64 hexadecimal characters. This runs through the browser's WebCrypto API, the same audited implementation used for TLS, rather than a JavaScript reimplementation.
How to use it
- Paste the text you want to run through sha-256 hash generator.
- There is nothing to configure — the result updates as you type.

Questions
Is SHA-256 safe for storing passwords?
Not on its own. It is secure as a hash but far too fast for password storage — a GPU tests billions of candidates per second. Password storage needs a deliberately slow, salted function: bcrypt, scrypt or Argon2.
How does this compare to SHA-1?
SHA-1 is deprecated. A practical collision was demonstrated in 2017 (SHAttered) and the cost has fallen since. Browsers and certificate authorities dropped it years ago; there is no reason to choose it for anything new.
What does SHA-256 Hash Generator use to do the work?
WebCrypto computes the digest natively — all of it running inside this page rather than on a server.
