5-word (160-bit block) ARX cipher from the DarkCrypt Total Commander plugin: 80-round construction over 5 state words with a 4-group rotating boolean function (xor / (NOT.OR).XOR / xor / AND-XOR), an RC5-style + embedded-S-box key schedule, and a secondary RC4-KSA-like table permutation stage. 160-bit block, 512-bit key.

| Issue | Description | Mitigation |
|---|---|---|
| Non-standard, unanalyzed design | Custom 5-word ARX construction with no public cryptanalysis; unusual RC4-KSA-derived round-key table; not recommended for real use. | Use AES or another vetted cipher. |
3 vectors ship with this algorithm and run in the test suite. Byte values are hexadecimal.
