Unzip encrypted zip #37

Is there a way to unzip an AES encrypted zip? Can't unzip properly with this type of zip file...

mattconnolly commented 10 years ago

I don't know. This cocoa pod is a wrapper around the minizip library. If the minizip library cannot do it, then this library will not be able to help you.

In crypt.h:

/*
...
The new AES encryption added on Zip format by Winzip (see the page
http://www.winzip.com/aes_info.htm ) and PKWare PKZip 5.x Strong
Encryption is not supported.
...
*/

So the zip can't be unzipped. Thanks anyway : )
