Beating the odds in internet security is the safe way to know your data is secured. For example encryption is the best we have today. You do know the chances of a brute force attack hits the right key? 1 in a number so big that the entire atoms in the Universe are nothing. Why is security an odd? Because there is no 100% safe system. There are 99.999% safe systems but no 100% system, and probably never will. Even Quantum encryption is far from being perfect, it’s just another step in the stair case of security.

At this moment the only way to break the best public encryption is discovering the right key either by brute force or by user mistakes. Getting the key from RAM right after the computer goes off is another tactic that works almost perfectly when the RAM is cooled. When you turn your computer down, the key will be in the RAM for about 24 hours and for as long as 2 weeks if the RAM is cooled. Anything that exposes your key is a critical threat to your security.

The most important part in security today is not learning and implementing algorithms but in protecting the key. The only hole your castle has is the key of the door.

How to protect your keys? Yes keys because you are not crazy enough to use the same key for your entire digital life. One fake website, one website with no SSL or a website with the password database open can make you more naked than a baby right after born. The program that works the best is Last Pass. All information there is encrypted with the master key and transferred using the latest AES so the only bad thing can be your lack of care for the master key. Give an unique key to each website and email then let Last Pass store it. For the passwords for offline applications just use a secure note. The master key should be carefully stored in an encrypted Pen drive.
