常见问题

Quick answers.

Are my files uploaded to your server?

No. The hashing process uses the `SubtleCrypto` interface in your browser to read the file locally. Your data remains entirely on your machine.

Which hash algorithm should I use?

SHA-256 is the current standard for security and integrity checks. MD5 and SHA-1 are provided for legacy compatibility but are no longer considered cryptographically secure against intentional tampering.

Can I hash very large files?

Yes. Since the browser reads the file directly from your local disk without uploading, you can hash multi-gigabyte files quickly, limited only by your device's hardware speed.

Why does the hash not match the one provided by the author?

Even a single byte difference will result in a completely different hash. Ensure the file downloaded completely and that you are comparing it against the correct version's checksum.
