FAQ
Frequently Asked Questions
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.
