Hash Generator
MD5 / SHA-1 / SHA-256 / SHA-384 / SHA-512 — text or file, all client-side.
Which hash should I use?
- SHA-256 — default for most uses. Git, TLS certificates, Bitcoin.
- SHA-512 — stronger; modern password hashing (with salt/iterations).
- MD5 / SHA-1 — broken cryptographically; OK only for non-security checksums / dedup.
- SHA-384 — often used in TLS 1.3 suites.
We compute SHA using the browser's built-in Web Crypto API. MD5 is computed via a local JS implementation (the Web Crypto API deliberately doesn't expose MD5).
