SHA3-384 is a high-security SHA-3 member producing 384-bit hashes via Keccak sponge with 192-bit collision security — suitable for quantum-resistant applications.

Why SHA3-384 over SHA3-256?

192-bit vs 128-bit security margin at the cost of larger output. For long-term hash storage or quantum resistance, the extra bits provide meaningful protection.

Is SHA3-384 quantum-safe?

No hash is truly quantum-safe, but SHA3-384 offers stronger resistance. Grover's algorithm would reduce it to 192 bits, still well beyond brute-force feasibility.

Where is SHA3-384 deployed?

High-security government systems, long-term digital archives, and applications requiring NIST's highest SHA-3 security level for digital signatures.

SHA3-384 vs SHA-384 performance?

SHA3-384 runs at roughly half SHA-384's speed on most CPUs due to Keccak's larger internal state. The security benefits often outweigh the performance difference for critical applications.
