"As for the part about "hacking and anti-hacking algorithm", I have no
clue what you're talking about. Should I drink a couple of beers and try
again ?"
An algorithm is the path (a logic with a mathematical analog) followed
by code (all code/programs have an algorithm). If you want a better idea
(without the classes in calculus and advanced mathematics) watch the TV
show "Numbers". Hackers are (fundamentally) computer scientists, using
mathematical algorithms to hack, and crack, systems. Because all
algorithms have an opposite (anti) algorithm, hackers use their skills
to break the code of another program. (In the encryption case), they
aren't after the key - they are going to attack the code, the program -
with worms and viruses. The goal is to lock you out, even with the key.
As for the camouflage recommendation, there are camouflage algorithms
that exist. However, once an algorithm is release, it's only a matter of
time before the anti-algorithm is found. So, I will not release what I have.
BTW - for those interested, Google, "The history of core wars." ; this
is the origin of much of hacking. (As well, Jobs and Gates were both
hackers.)
