WPA and WEP

I did'nt quite get the hang of what wpa actually was however i do know that virtually every wep protected network can be "cracked" with a little time and a computer. It doesent matter if its a 64 bit encryption or a 256 bit, Since most wep crackers out there today scan for packages wich are weak. In other words they sort out packets leaking info about the wep key. Even the slightest bit of info about the wep key will speed up the "cracking" process. With own experience i can say it's not easy but it's possible. Anyone who really wants to acess a wep protected network can do so with minimal effort. It's just to wait for the gathering of the packages to finish and then start cracking them. Time is the answer to this question.
