What Is SHA3-384?

SHA3-384 is the 384-bit SHA-3 (Keccak sponge) variant — 96 hex characters of output with a 768-bit capacity backing its security. It pairs naturally with P-384 elliptic curves in suites that want matched security levels.

Capacity and Security

SHA-3's security comes from its capacity parameter, not just output length: SHA3-384 reserves 768 bits of the 1600-bit state, giving collision resistance well beyond what any attacker could approach — including, conservatively, quantum-assisted ones.

When It Appears

High-assurance government and financial protocols, and standards that mirror the SHA-2 size ladder (224/256/384/512) in Keccak form. If your spec names it, this generator produces the exact NIST digest.

How to Use the SHA-3 384 Hash Generator

SHA-3-384 is the 384-bit member of the Keccak-based SHA-3 family, standardised by NIST in 2015 — it is the strength level recommended for high-security and classified-grade hashing.

Example

Hashing the word hello with SHA-3-384 always produces 720aea11019ef06440fbf05d87aa24680a2153df3907b23631e7177ce620fa1330ff07c0fddee54699a4c3ee0ee9d887 — 96 hexadecimal characters, the same every time.

Frequently Asked Questions

Why use SHA-3-384 instead of SHA-3-256?
The 384-bit variant offers a higher security margin, roughly equivalent to 192-bit symmetric security. It is the digest size paired with 384-bit elliptic curves in high-security suites.

Where is SHA-3-384 actually used?
It appears in TLS 1.3 cipher-suite identifiers, NSA Suite B-style guidance and government systems that standardise on the 384-bit security level.

Is SHA-3-384 just SHA-3-256 with more output?
No — Keccak produces each size with its own parameters and capacity settings. Digests from different SHA-3 sizes of the same input are completely unrelated.
