I Didn't Encrypt the Files. I Changed Who Windows Allows to Touch Them.

When I started building ATLOCK, I initially thought about file protection as an encryption problem.

Then I realized something:

Encryption and access control solve different problems.

So for ATLOCK's File Guard, I went in a different direction.

Instead of encrypting every protected file, ATLOCK uses Windows NTFS Access Control Lists (ACLs) to control which identities are allowed to access protected files and directories.
