About SHA3-256

SHA3-256 is a member of the SHA-3 cryptographic hash family standardized by NIST in 2015. It produces a 256-bit (64 hex character) hash using the Keccak sponge construction.

SHA3-256 provides the same security level as SHA-256 but uses a fundamentally different design, making it immune to length extension attacks.
