Frequently Asked Questions
SHA3-384 provides 192-bit security (collision resistance) with a 384-bit output, offering a middle ground between SHA3-256 and SHA3-512. It's used in high-security applications requiring more than 128-bit security but where SHA3-512's 512-bit output would be excessive. Common in government and defense applications.
SHA3-384 is used in high-assurance environments: (1) TLS 1.3 cipher suites for high-security connections, (2) Government and military systems requiring 192-bit security, (3) Long-term document signing where extended security margins are needed, (4) Certificate chains requiring higher security than SHA-256.
Both provide 192-bit security with 384-bit output, but use different internal designs. SHA3-384 uses Keccak sponge construction with 768-bit capacity, making it natively resistant to length extension attacks. SHA-384 uses Merkle-Damgård construction and is essentially truncated SHA-512. SHA3-384 has different performance characteristics and security assumptions.
