Is it possible to add support for QuaZIP to work with archives in which the files are password protected by the AES compression method ? I looked at the source code of minizip library and there are relevant definitions.

In the tickets I found no reference to this topic so sorry if this question has already been discussed.

    I'll look into it. I think it can be done, but will definitely require some work, especially for compressing... For decompressing it could be easier, but still. I'll post more when I figure out anything.

    Hi, I am also very interested in AES support. Read support alone would be great!

    I found this fork of MiniZip which brings support for AES and many other things, maybe this helps: https://github.com/nmoinvaz/minizip

    Now that's good news! I'll look into it when I have time. The problem is, Minizip in QuaZIP includes some adjustments needed for it to work with non-file QIODevices, like QBuffer. I'll have to re-apply those adjustments to this Minizip fork or just borrow the appropriate parts of its logic. Both ways, it's not trivial.
