RLPack is a software that gives you the power to compress your executables and dynamic link libraries in a way that keeps them small and has no effect on compressed file functionality. Further more RLPack protects your files from modification and has several protection options which help protecting your files from being changed or cracked. But compression and protection does not stop there. RLPack with iBox module can pack your dynamic link libraries and place them inside the main executable so they can not be modified. They are extracted directly to memory (or optionally to disk) hiding their presence and enabling you to keep your dynamic link libraries safe from being used by third party programs or users.
