So you have just admitted to reverse engineering VAC, which is a part of
STEAM.
This is a violation of the SSA and you are lucky if your Steam account
is not disabled.

software accessed via Steam without the prior consent, in writing, of

The reason I said that we don't know how VAC works is WE DONT. The
things that we do know are that it works off of some kind of checksums,
which is the only way that it could not produce false positives.
Being an anticheat developer myself, I wouldn't even think about making
the one I work on support any VAC games, because the risk is far too
high. We will be sticking to older games and games which use punkbuster
(Which can definately be turned off).
