FAQs

Are files uploaded to generate hashes?

No. File hashing uses the browser Web Crypto API on your device.

Which hash should I choose?

SHA-256 is a good default for modern checksums. SHA-1 is included for compatibility checks only.

Is a hash the same as encryption?

No. Hashing creates a one-way digest and cannot be reversed to recover the original input.
