So maybe it's an older version than our zip2john can handle. However,
when I create a sample file using zip 3.0, zip2john also shows "ver 14"
(btw that is actually 0x14 so same as the "20" reported from 7zip) so
I'm not sure what's happening here.
Would you be able to supply a sample file that has this problem, and a
known password? Either publicly or for a narrower audience (normally for
pkzip it would be JimF but he seems to be unavailable right now so maybe
me instead).
BTW TOPS-20 wow hardcore ^^
