Frequently asked questions

What is a SHA-256 hash?

SHA-256 is a cryptographic hash function that turns any input into a fixed 64-character hexadecimal string. The same input always produces the same hash, so it's useful for verifying data integrity.

Can I hash a file?

Yes. Drag and drop a file or choose one with the picker, then generate the hash. The file is read and hashed entirely on your device.

Is my data sent anywhere?

No. The SHA-256 calculation runs entirely in your browser using the Web Crypto API. Your text and files never leave your device.

Is SHA-256 reversible?

No. SHA-256 is a one-way function. You cannot recover the original input from a hash — that's exactly what makes it useful for comparisons and integrity checks.
