Wicker-98 block cipher from the DarkCrypt Total Commander plugin: 35-round unbalanced ARX network on four 32-bit words with a rotating accumulator folded into a cycling target word, plus 4-word key whitening. 128-bit block, 128-bit key.

| Issue | Description | Mitigation |
|---|---|---|
| All-zero weak key | The network is pure ARX with no round constants, so it fixes the all-zero state, and an all-zero key makes the whitening words zero too. The all-zero block is returned unencrypted under that one key. | Never use an all-zero key. |
| Unanalyzed construction | Non-standard, publicly unanalyzed cipher of unknown provenance; not recommended for real use. | Use AES or another vetted cipher. |
6 vectors ship with this algorithm and run in the test suite. Byte values are hexadecimal.
