Thanks for the info. I was unaware that hashcat was being developed solely for competition - just thought it was a general purpose "password recovery" suite, like the the web page info indicates. I apologize for the misunderstanding, in any case, and would not have asked at all if there hadn't been a distinct feature request forum where someone had already mentioned zip support previously.

Thank you for the site, but I pointed out that program (Accent Zip Password Recovery) in my original post and noted there that it only supports AES-based zip encryption, which was winzip 9.0 and later - I was looking for winzip 8 and older, without the AES.

There are already quite many very good highspeed rar or zip crackers!
Like ElcomSoft Distributed Password Recovery!
Look for it!
As I mentioned in my original post, I have already tried every available traditional cracking method, including those available from Elcomsoft. The problem is that none of them heavily support multithreading, let alone GPUs, for zip files, which seriously limits their speed. The only one that DOES support GPUs, the Accent one mentioned above, is only for AES zip files.
The one product you mention, the Distributed Password Recovery package from Elcomsoft, does seem to be quite fast, using up to 64 cores as well as GPUs, but unfortunately it does not support zip files at all. You can check the full files support list at the end of the page for it.
