Keccak-512 as used by the DarkCrypt Total Commander plugin: the original SHA-3 round 1 submission (Keccak version 1, 2008), Keccak[r=512, c=1088, d=64] with 18 rounds of Keccak-f[1600] and the version 1 padding that encodes the diversifier and rate. Differs from later Keccak-512 and SHA3-512, which use 24 rounds, a 576-bit rate and pad10*1; matches the published round 1 known-answer tests.
