Subject: compress / decompress zip file in WinZip 11 format

Hi



I am trying to decompress a zip file created by our PC side software
which using WinZip 11 API. This file has password protected and using
AES (256 bit)  to encrypt.



So far I tried unzip command line, which return unsupported compress
method. I check zlib and minizib, which said does not support WinZip new
encrypt algorithm. I got a source code of p7zip, but it has so much
information. It will take time to extract what I want out from it.







Does anyone have experience on this?



Any suggestion will be appreciated.







Thanks

Hebin
