Password Protecting External EXE Files?
<p>I have a question about programs that password EXE files on the users PC.
I actually wanted to know how these work, the ones that allow the passworded EXE to run on a PC without the software installed.</p>

<p>Do they add something in the program, or do they somehow replace it with a program that runs the exe in memory?</p>

<p>Now, I wanted to know how this could be done in C#, is it even possible?
I would like to be able to create authentication of my own for the programs on my computer(I assume some would be in C++, some in DotNet and what ever other languages popular games/programs are created with).</p>

<p>Thanks to anyone who can answer/help me :)</p>
