Frequently asked questions
How is SHA-512 different from SHA-256?
It produces a longer 512-bit digest; both are one-way and secure for integrity use.
Is the hashing local?
Yes — it uses the Web Crypto API in your browser.
Can I hash a password with it?
For storage, use a slow salted KDF (bcrypt/argon2) server-side, not a raw hash.
