The obscure “Iraqi” block cipher as shipped in the DarkCrypt Total Commander plugin: a 5-round balanced Feistel on two 128-bit halves of a 256-bit block, with a 160-bit key and key-dependent S-boxes/P-box.

| Unvetted / hoax-origin cipher | The Iraqi cipher is widely regarded as a hoax of unknown provenance and has received little serious analysis; the DarkCrypt packaging is unmodified from that anonymous source. | Use AES or another vetted cipher. |
3 vectors ship with this algorithm and run in the test suite. Byte values are hexadecimal.
