SHA Hash Generator

SHA (Secure Hash Algorithm) family. All four variants here are computed by the browser's crypto.subtle.digest — the W3C Web Crypto API, available in every modern browser.

Which SHA to use

SHA-256 — the modern standard. Used by Bitcoin, TLS certificates, most signatures.
SHA-512 — bigger digest, slightly stronger. Preferred on 64-bit hardware; slower on 32-bit.
SHA-384 — truncated SHA-512. Used in NSA Suite B.
SHA-1 — deprecated for security but still used in Git commit IDs and some legacy systems.

For a non-cryptographic hash use MD5.
