The purpose of password is not really effective as a form of
"protection" but rather more like "deterant"
The idea is to make it painful and tedious to hack for casual
amataur hackers
If ppl seriously want to hack you..no matter what password length
or encryption you use, they will still want to (given enuff time
they may even be successful)
Its just like a locked door..if thieves want to break in they will
break no matter how many locks u install and those not so hardcore
thieves see if you got so many locks then sian 1/2 and then move on
to a easier prey.
