Frequently asked questions

Are hashes reversible?

No. Cryptographic hashes are one-way functions — you cannot recover the original input from the hash.

Is input uploaded to a server?

No. Hashing is computed locally in your browser.

What is SHA-256 used for?

SHA-256 is widely used for data integrity checks, password hashing (with a salt), digital signatures, and blockchain verification.

Is the hash generator free?

Yes. Free, no sign-up, no limits.
