SHA Hash Generator

Compute SHA-1/256/384/512 hashes using the Web Crypto API, entirely on your device.

Generates SHA-1, SHA-256, SHA-384, and SHA-512 hash values from text. Used to check data integrity or match checksums.

How to use Hash (SHA)

  1. Enter the text.
  2. Choose the SHA algorithm.
  3. Copy the resulting hash string.

Frequently asked questions

Can a SHA-256 hash be reversed?

No. Hash functions are one-way — you can't derive the original data from the hash value.

Which SHA algorithm should I use to store passwords?

You shouldn't use plain SHA for passwords; use a dedicated algorithm like bcrypt or argon2 on the server side.
