Encryption key cracker.

[Sirrus]

Hey folks.

I'm not talking about breaking actual security keys, of course, but I was wondering if there was some kind of tool that used my computer to its full power to do mock brute force attacks. I'm curious how fast my computer is for raw math and I wanted to see how fast it could crack various encryption keys.

Any half-decent encryption key would take 100 years with all the processing power in the world to break.

Really? A 128bit key consisting of letters and numbers, which only has 62^16 combinations would take 100 years?

62^16 is 47672401706823533450263330816 combinations, so yeah it'd take a long time.

But if you've got the combined processing power of every computer in the world...

You're going to magically link up every single computer in the planet, old and new, to crack a 128-bit key?

Can anyone explain Encryption keys without being a douche and linking me to the wikipedia page or telling me to google it? I don't feel like swimming through walls of text, I would just like to know what they are and how they work.

Say you have one billion computers each attempting a set of combinations. They'd have to each do an average of about 15,116,189 tries per millisecond in order to complete the task in 100 years.

Basically we're talking about trying to go through all the arrangements of a 128 bit key, which looks kind of like this:

D8zRLhzQxUNz6ZjK

(16 characters= 8bits per character * 16=128 bits).

But because you can have numbers, lower case or upper case letters in each spot you're looking at (26+26+10) times the number of slots there are, so 62^16 which is 47672401706823533450263330816 .

What exactly are the 'bits' per character?

[Sirrus]

What exactly are the 'bits' per character?

bit is a 1 or a 0, binary. Each character is comprised of 8 bits, or one byte. There are 256 characters that can be expressed by some arrangement of eight ones, eight 0's, or some combination thereof.

Also, ontopic, by some fast and dirty calculations (the number of arrangements divided by the clock rate on each cell of my processor) I figured that a 64 bit key would only take about two days.

Correct?

ive got a 256bit encrypted zip file with naked pics from an old gf.

im unable to open it still, but someday
