We haven't read the whole thread but just from an observation prospective any password or decipher can or will eventually be broken. Not to run you scared, you have to consider why would anyone want to break your password or pin? It is however common sense to create good strong passwords, but of course some of us can be lazy nor have the ability to remember the amount of pins and passwords we need to remember these days (some can, some can't - that's one thing what makes us human)
If you have a strong password and pin, a good firewall (or even better a double firewall) then the majority of hackers will not bother or find out. We call them lazy hackers. Ones that look for loop holes but wont actually spend more than 30-mins to an hour trying to break in. Medium hackers and serious hackers are a little trickier to deter because they are for one more determined usually and have better skill levels (yes you have white hats, black hats etc - we aren't necessarily referring to those) regardless how strong your password is. You also have to consider phishing and keystroking which in any case would't make any difference how great your pin or password is.
To avoid an essay on this, a really good hacker will break into any system or password.
If you really wanted to, anyone could go onto an open home network and hack into their computer with relative ease. It does not make sense to us that you would not put a password on your home router - we would strongly advise you putting a decent password on your network.
We will no doubt run a good few articles on this in our Facebook page shortly as we have a huge amount of experience in this area and will look to put together an E-book for people the future.
