Bit-oriented block cipher from the DarkCrypt Total Commander plugin: 16 rounds of table-driven bit substitution, cascade and permutation over a 64-bit state, keyed via a 588-byte table expanded from a 128-bit key. Original/obscure design (not a published algorithm).

| Issue | Description | Mitigation |
|---|---|---|
| Unanalyzed proprietary design | MBC2 has no public specification, security proofs, or third-party cryptanalysis; its bit-level structure has not been vetted. | Use AES or another vetted cipher. |
3 vectors ship with this algorithm and run in the test suite. Byte values are hexadecimal.
