What Is SHA-3/384?

SHA-3/384 is a cryptographic hash function from the SHA-3 family, producing a fixed 384-bit (48-byte) hash output. Based on the Keccak sponge construction and standardized by NIST as FIPS 202, SHA-3/384 offers a higher security margin than SHA-3/256 — providing 192-bit collision resistance — while remaining faster than SHA-3/512.

This free online tool generates SHA-3/384 hashes instantly from any text input — no downloads, no accounts, no hassle.

Why Choose SHA-3/384?

SHA-3/384 sits in the sweet spot between security and performance within the SHA-3 family:

  • 192-bit collision resistance — Significantly harder to attack than 128-bit (SHA-3/256)
  • Independent from SHA-2 — Built on a completely different mathematical foundation
  • Immune to length-extension attacks — No need for HMAC wrappers for secure message authentication
  • TLS 1.3 compatible — Used in modern transport layer security cipher suites
  • Balanced performance — Faster than SHA-3/512 while offering stronger guarantees than SHA-3/256

SHA-3/384 vs Other Hash Functions

Compared to SHA-384 (SHA-2)

SHA-384 (SHA-2) and SHA-3/384 both produce 384-bit outputs, but they use entirely different internal algorithms. SHA-384 is a truncated version of SHA-512 using Merkle-Damgård, while SHA-3/384 uses the Keccak sponge. Having both available provides algorithm diversity — critical for long-term cryptographic resilience.

Compared to SHA-3/256 and SHA-3/512

SHA-3/256 is faster but has lower collision resistance (128-bit). SHA-3/512 is stronger but slower and produces longer hashes. SHA-3/384 offers the best balance for applications needing more than 128-bit collision resistance without the overhead of 512-bit output.

How to Use the SHA-3/384 Generator

Best Practices

  • Use SHA-3/384 for high-security applications — When 128-bit collision resistance isn't enough
  • Pair with proper key management — A strong hash is only as good as your overall security architecture
  • Store hashes securely — Protect hash databases from unauthorized access
  • Document your hash algorithm choice — For compliance audits and future migration planning

Frequently Asked Questions

What's the difference between SHA-384 and SHA-3/384?

They're from different hash families. SHA-384 is part of SHA-2 (Merkle-Damgård structure), while SHA-3/384 is part of SHA-3 (Keccak sponge). Both output 384 bits, but their internal algorithms are completely independent — providing defense in depth if one is compromised.

Is SHA-3/384 overkill for most applications?

For general-purpose hashing, SHA-3/256 is usually sufficient. SHA-3/384 is ideal when you need higher collision resistance (192-bit vs 128-bit) or when regulatory requirements mandate it, such as in government or financial applications.

How long is a SHA-3/384 hash?

A SHA-3/384 hash is always 96 hexadecimal characters (384 bits / 4 bits per hex char). This is 50% longer than SHA-3/256 output (64 chars) and shorter than SHA-3/512 (128 chars).

Can SHA-3/384 hashes be cracked?

SHA-3/384 is considered cryptographically secure. With 192-bit collision resistance, a brute-force attack would require approximately 2^192 operations — far beyond the capability of any current or foreseeable technology.
