Protect CAB file with password and read this with a DLL

Hi All,

First my english is not perfect.

I want to implement code protection for our simulation models (aircraft).

My questions:

1. How to protect a CAB file (MsZip) with a password? ZIP programs can not do that.

2. A dll (c ++ - I have created) for a game read this password protected CAB file (content).

Possible?

Regards,

Alex
