How it works
The Hash Generator computes a SHA-256 hash of your input text entirely in your browser using a pure JavaScript implementation, so your data never leaves your device.
Frequently asked questions
Can I reverse a hash back to the original text?
No. SHA-256 is a one-way function; hashes cannot be reversed, only compared against known values.
