My professor asked all of us (individually) to download the ramdisk driver source from Microsoft Driver Sample repository from github. He asked us to do the following thing 1. Modify the driver so that it only works if we provided the correct password (through user-mode application(created by us)) 2. Ramdisk is non-persistent storage because it stores data on ram. So, our task is to remove RAM processing altogether from driver and do all the i/o (requested by user) on some predefined file on our storage disk. 3. The last task is to encrypt every incoming data and decrypt every outgoing data using Tiny Encryption Algorithm.
