    Help w/ DLLs and a Security Prog.

    Hi Guys, Long time no see. Anyway i have been trying to make a security encryption type of prgram that forces you to log in then it allows you to encrypt things. The only thing is i wanted it to be so that the password and encryption algorithm would be stored on a usb flash drive. I figured a dll would be perfect for this, can anyone give me and address to a tutorial or other information? Thanks!

    ~PS- I have a computer with Windows XP Home edition on it and i cant get programs to save files to the computer. Any suggestions? The same code works on this computer (WIndows ME) Thanks AGain!

    Are you referring to an example of the encryption or I/O?

    If I read this right...

    You want to write an app

    User selects file
    De/en-crypt file

    must store encryption key remotely

    No need for a DLL. A DLL is a library. Allows you to share code between apps. Each key would have to be hard coded into each DLL individually.
    Key is just data so can store as a file.
    Problem is if key gets 'lost' data is also lost..

    Which bit do you need help with?
