Thank you for reporting this, @tonyvetere! I hope @magnumripper will add a more useful comment here and will help us label this issue (are we in fact missing support or do we maybe have a bug or something else?)

I'm assuming it's an unsupported algo (as of yet), just like bzip2 in #4124, so labelling as enhancement. I'll see if I can produce a test vector for a starter.

@andar1an you might be able to add support for this (at least in zip2john) while at it, if you work with #4124.
