I didnt get you. Do you think I have not programmed in C++ and
writing code to implement encryption/decryption of files.
By the way why do you think I dont know C++?
If you are reffering to the above code, it is just the pseudo code
that
I have written. It is to give an idea about what I want.
Thanks
