FAQ

Is my file uploaded?

No. Hashing uses the Web Crypto API in your browser. The file never leaves your device.

Which hash should I use?

SHA-256 for checksums and integrity today. MD5 and SHA-1 are fine for detecting accidental corruption but are not secure against tampering.

Can I verify a downloaded file?

Yes. Choose the file, then compare the SHA-256 with the value published by the download page.

Is there a file size limit?

Files of several gigabytes work; hashing runs at hundreds of MB per second.
