Veelgestelde vragen
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.
