Undocumented 128-bit block cipher from the DarkCrypt Total Commander plugin: a 12-group substitution-diffusion network over a 256-bit key, built from two fixed 256-byte tables and one fixed 14336-byte seed table, all mixed into per-key BigSbox and CTable schedules via an order-dependent, self-referential two-pass self-encryption process. No public specification is known.
