Using Vice without Steam

What is this?

This is a Steam port of VICE that is built to not depend on Steam. This modification works on Windows and Linux.

Compiling on Windows

• First you need to create a new Empty VisualC++ Console Project that will compile this code into an executable.
• Add public/IceKey.cpp into your project
• Setup the include paths in your settings to include public/ (for the header file)
• Copy the code below into main.cpp, and compile.

Compiling on Linux

• Copy the makefile into a file called Makefile
• edit the Makefile to refleft the path to your SDK_ROOT/public/ directory
• make

Wildcard Version by Red Comet

I really like what you did with vice, so I took my favorite part of steam vice and added it to your vice.

This new program will accept the wildcard ' * ' in the filename, so you can put this exe in with all your txt's and encrypt them all at once.

Instructions:

Copy this new Main.cpp file into your old one, completly replacing the old one

Make a new header file called osdir.h and copy the contents of the second section of code below into it.

Compile

Not sure if it works in Linux yet, but it should
