Your hash will appear here
Paste some text, pick an algorithm and press the button.
Create a SHA-256, SHA-384 or SHA-512 hash of any text without sending it anywhere.
How it works
For integrity checks, signatures and debugging.
Any length; the same input always produces the same hash.
SHA-256 is the usual choice; SHA-384 and SHA-512 give a longer digest.
The result is a hexadecimal string you can compare or store.

No. A hash is one-way by design — but short, common inputs can be guessed by trying them, so a hash is not a place to hide a secret.
SHA-256 unless something specifically requires otherwise. The longer variants are not more secure in everyday use, just longer.
No. Password storage needs a slow, salted algorithm such as bcrypt or Argon2; plain SHA is far too fast for that job.
No. The digest is computed by the browser’s Web Crypto API, locally.
