Not directly, but you can use it to feed candidate passwords to a ZIP
password cracker.  You would use the --stdout option for that, possibly
redirecting the output to a file or to a named pipe (if the actual ZIP
cracker is unable to read from its standard input).

I have some shareware (non-free) ZIP password crackers listed here:

Unfortunately, these are Windows-only.  A couple of (semi-)free ZIP
password crackers with source code are:

	http://www.goof.com/pcg/marc/fcrackzip.html
	http://www.unix-ag.uni-kl.de/~conrad/krypto/pkcrack.html

and you should be able to find more with a search engine.
