SHA-3-256
RecommendedSHA-3-256 is part of the SHA-3 family based on the Keccak algorithm, selected through a NIST competition in 2012. It provides a fundamentally different design from SHA-2, offering an alternative if SHA-2 is ever compromised.
What is SHA-3-256?
SHA-3-256 is a recommended cryptographic hash algorithm that produces a 256 bits (64 hex characters) output. SHA-3-256 is part of the SHA-3 family based on the Keccak algorithm, selected through a NIST competition in 2012. It provides a fundamentally different design from SHA-2, offering an alternative if SHA-2 is ever compromised. It is classified as medium in performance and commonly used for post-quantum cryptography preparedness and environments requiring diversified hash algorithms.
