I want to create a file system filter driver, which will encrypt the data while writing to disk and will decrypt the data while reading. (I hope one needs to use IRP_MJ_WRITE and IRP_MJ_READ)
OS: Windows XP
I've the DDK/IFS kit.
I'm modifying the example of SFilter in IFS kit. I want this file sytem filter driver to work only for Floppy drive.
Any example source code, pointers to specific documents will be helpful.
