Can encrypted folders or files be prevented from reuploading?

Question

Can encrypted folders or files be prevented from reuploading?

JohnCTX 636

How could users encrypt folders or files, so that it can be prevented from uploading?

Would it take a console command line library in Windows shell?

I am certain that there are many options for users who want to their future products from reuploading, so that merchants get their money's worth for every customer.

Hello @JohnCTX , you can refer to "Handling Encrypted Files and Directories" and "Example C Program: Encrypting a File" if you want to achieve this purpose vis Win32 APIs.

If you are an application developer and wish to prevent customers from sharing your app with others, then your best bet is to implement some kind of licensing technology who's "key" is based on the underlying hardware. You would be better off asking this question in a developers specific forum.

You may achieve this using DLP and Information Protection Policies and these are set of policy which gives you ability to control your files and data. It has nothing to do with encryption but it is about managing data and make sure users won't be able to share data where they are not suppose to share in any form such as upload, email and so on.
Here is one example:
