FAQ
Is my text or file uploaded?
No. Hashing uses the Web Crypto API built into your browser. Text and files stay on your device.
Which algorithm should I use?
SHA-256 is the modern default for checksums and integrity checks. SHA-512 is stronger but longer. SHA-1 is legacy only — avoid it for new security designs.
Can I hash large files?
Yes, within browser memory limits. Very large files may be slow or fail on low-memory devices — that's a browser constraint, not a server limit.
