Custom block cipher bundled with the DarkCrypt Total Commander plugin. Four-branch structure combining IDEA-style modular multiplication, four keyed byte-substitution tables, and 64-bit rotate mixing over 16 body iterations (32 sub-rounds). 128-bit block, 256-bit key, big-endian words. No public specification is known.
