The amount of obfuscation going on here is very impressive. It always makes me wonder how these things are even written and designed in the first place. I seem to recall a C++ protection library that would allow you to define custom versions of types like int and long. It would use operator overloading to allow you to use the types in a fairly normal fashion, but underneath these operators would actually be implemented as a very complicated virtual machine. This way, your algorithm code could look fairly normal but it would compile to an absolute beast of a protection layer.
