situation in Germany is somewhat unclear about "software tools meant to commit crimes". It's a very controversally discussed topic, and not really simple. Anyway hosting of *tools* is not illegal, and if you're for example a professional penetration tester then all sorts of cracking tools are in your daily toolbox.
However cracking the neighbour's WLAN just for fun is definitely ILLEGAL almost everywhere in the world.
