About this tool

A hash is a fixed-length fingerprint of data. Compare the SHA-256 of a downloaded file with the one the publisher lists to check it was not changed. Hashing uses your browser and the file is never uploaded. MD5 is not offered because the browser does not provide it.

Questions

Is my file uploaded?

No. It is hashed in your browser.

Which algorithm should I use?

SHA-256 for most checks. SHA-1 is only for old systems.

Can a hash be reversed?

No. A hash cannot be turned back into the original data.
