Try adding all such components, one on each line, to a short wordlist eg. "components.txt". Add punctuation and numbers (either simply digits 0 through 9 on separate lines, or/and longer numbers like 2020 if you know them) as well, on separate lines. Then use PRINCE mode. > The first issue is that I believe I need to use zip2john.exe to get the > hash from the zip file.

What does "zipinfo <file>" or similar tool say? Or just "zip -l <file>". It sounds like you got a proper hash (you need to redirect that screen output to a file) and the warning you got later is probably from some other (not encrypted) file in the archive. Perhaps you accidentally added a non-encrypted version to the archive?

No, if it's zip format, zip2john is needed. zip2john archive.zip > hashfile.txt john hashfile.txt --prince=components.txt magnum
