Hi,

I have some question, regarding the Windows File System Encryption/Decryption on the fly, i.e.

in-memory while performing different file I/O operations?

In technical term, I need some sort of DLL (have NTDLL APIs hooking logic implemented) or a File

System Filter driver (just like filespy legacy driver or swapBuffers minifilter driver) to

support encryption/decryption of all the files present in a specific folder.

I already have IFS kit with me, and using that I have used swapBuffers minifilter code to meet

my above reqirements. And I have been able to alter the read/write IO operations for .txt file

invoked, through Editplus utility, but still not able to read the altered contents of .txt file

through notepad.exe.

Though some codes are available on net but it does not perform with all types of file. How to

perform these sort of operations.

I would appreciate a kind response from anyone which could be helpful for me to proceed further

in this direction.

Best Regards
