How it works
SHA‑1, SHA‑256 and SHA‑512 are computed with the browser's built-in crypto.subtle.digest. MD5 isn't part of the Web Crypto API, so it runs through a small self-contained implementation on this page. MD5 and SHA‑1 are broken for security — use them only for checksums and de-duplication, never for passwords or signatures. Want to build this yourself? Read the step-by-step guide.
