SHA-256 Hash Generator

About this SHA-256 Hash Generator tool

A hash function turns any input into a fixed-length fingerprint. SHA-256 produces a 64-character hexadecimal result. The same input always gives the same hash, and a tiny change in the input changes the hash completely. It is used to verify files, detect changes and in many security systems. Hashing is one-way: you cannot get the original text back from the hash.

How to use it

1. Type or paste your text.
2. Click Generate.
3. Copy the SHA-256 hash.

Example

hello  →  2cf24dba5fb0a30e26e83b2ac5b9e29e1b161e5c1fa7425e73043362938b9824

Frequently asked questions

Can a SHA-256 hash be reversed?

No, but short or common inputs can be guessed by trying many candidates, so do not rely on plain SHA-256 to store passwords.

Should I use SHA-256 for passwords?

Not on its own. Use a slow, salted password hashing algorithm such as bcrypt, scrypt or Argon2.

Is my text sent to a server?

No. The hash is computed in your browser.
