SHA-3-512

Recommended

SHA-3-512 is the 512-bit output variant of SHA-3 (Keccak). It offers the longest standard hash output in the SHA-3 family and is used when maximum hash length and algorithm diversity are required.

What is SHA-3-512?

SHA-3-512 is a recommended cryptographic hash algorithm that produces a 512 bits (128 hex characters) output. SHA-3-512 is the 512-bit output variant of SHA-3 (Keccak). It offers the longest standard hash output in the SHA-3 family and is used when maximum hash length and algorithm diversity are required. It is classified as medium in performance and commonly used for high-security applications requiring algorithm diversity and long-term archival integrity verification.
