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

Question

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 to use ZipArchive (based on MiniZip) but it doesn't work. Anyone knows how to do this ?

Answer 1

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.
