How to unzip an AES encrypted zip file on the iPhone?

In my current iPhone project I need to decrypt zip files which have been encrypted using AES 256 method either on a Mac with StuffIt Engine or on Windows with WinZip.

I tried 开发者_JAVA技巧to use ZipArchive (based on MiniZip) but it doesn't work. Anyone knows how to do this ?

Added AES encryption support to Minizip contrib: https://github.com/nmoinvaz/minizip

I ended up buying a license for IPWorks ZIP library which works fine.

You should try to port (include) InfoZip sources, they are compatible with such encryption style. However, you should also check if the license for InfoZip is adequate for your circumstances.
