Security Through Obscurity

It never works...
http://en.wikipedia.org/wiki/PunkBuster
Because PunkBuster scans all of a machine's virtual memory, malicious users were able to cause mass false positives by transmitting text fragments from known cheat programs onto a high population IRC channel. When PunkBuster detected the text within user's IRC client text buffers, the users were banned.

Passwords are security through obscurity. Let's throw those away. Infact let's throw all encryption away, because it's just obscuring and thus bound to be unobscured. It's not safe! Remember "Security through obscurity" does not work. Never! Clearly passwords does not work.

Let's say you have a file full of seemingly random data. It's of no use to use, unless you know that it is encrypted, encrypted with a certain password. Unfortunately, these facts are obscured to you. Now consider how hard it would be for you to access the real content in said file. Hard, yes? Impossible no. Now consider how hard it would be for you to access said file if it had not been encrypted.  Not so hard right? So what was the point encrypting a file anyway, all it did was making it hard through obscurity, which we know is a farse. There is no point, that's why.
