SHA-384 — 384-bit — a truncated SHA-512 with a wide security margin

SHA-384 is based on SHA-512 and produces a 384-bit (96-char) output. It is used in high-security environments that need a longer hash than SHA-256.

Because it is built on 64-bit operations, it can be faster than SHA-256 on 64-bit systems, and it is resistant to length-extension attacks. It is used for TLS, code signing, and more.
