SHA3-512

The 512-bit member of the SHA-3 family. Same sponge construction, more capacity, slower throughput.

By ·

SHA3-512 is the 512-bit variant of the Keccak-derived SHA-3 family. Capacity is doubled (which boosts the security margin against generic attacks) but throughput drops correspondingly. It's the right choice when an enterprise policy mandates a SHA-3 family hash *and* the larger 256-bit security level; otherwise SHA3-256 is the more common pick.

Recommended uses

  • ·Compliance scenarios requiring SHA-3 family + 256-bit security

Known attacks / caveats

  • ·None practical.
