    A friend today asked me to bruteforce a zip file. I don't know anything about the password. So I began looking for some utilities...and I found Passware Password Recovery Kit. After 4 hours working on my quad core phenom2 3.4GHz it has crunched over 142.000.000.000 passwords....but still no luck with the right password! This utility claim to use GPU too but ATI is not used for this type of password recovery. Anyone using faster utilities? Is there something better than this?
    Now it's going at a rythm of about 4.000.000 passwords/second!

    It could take days or months. Especially on that system. It just doesn't seem worth it. Was your friend the one who password protected it.? I or maybe he's trying to get into somebody's personal documents. Be careful

    Also there was a utility that used the cuda cores of gpu instead of cpu.. But I can't remember the name

    With my i7 2600k I need to stay around 6-7 hours to crack a 3 digit password. Maybe is the program but i stoped long ago to try :)

    3 digits don't take that long. But as they get longer. It's harder to cracked

    yes he lost its password :(( and it was complicated too...because that software tryed a whopping 180.000.000.000 passwords without succcess...then i stopped it for now lol. Anyway 6-7 hours to crack 3 digit is really a way too much...on an i7 2600k too!

    Surely he must have an idea as to what the password is? If not then game over as that defeats the point of a password and if it was as simple as getting a readily available script to unlock it then there would be no point in passwords in the first instance. If this data that they have is that valuable that needs a password against it then surely they've got a backup of it somewhere else?

    Maybe i exagerated with the 6-7 hours but it was an exemple is to much to break a password and is not 100% guaranted

    Either way, look to my point about trying to crack passwords. Can be dangerous territory to step into for obvious reasons as we're talking about breaking security measures. As long as this is 100% legit and you are the owner of the original file then i'll let this thread stay open.

    I have used many times to unlock a zip file but what i got is -ve results but many of them are never unlocked even with using a password recovery software. Therefore i now always keep a backup of the file

    BadNoddy, don't worry...it was more like a challenge and curiosity to push me doing that. Only to see how much time it could take...and help him. But I'm already surrendering xD

    Have you tried gpgpu computation? It would make you decrypt much faster

    I would say its less about the hardware and more about the password used and the encryption method, look for software that utilises a rainbow list of some sort maybe?

    Isn't there a a program that just runs in the background and continues every time you fire up your computer? That way you might recover it in the long run...

    If I'm not mistaken, brute forcing a password has a time complexity of n! which is an incredibly long time.
    You'd need a program similar to this..
    int i = 1; // you're supposed to check every combination of 1 letter, 2 letters, 3 letters .... n letters.
    for (every char on keyboard){
    if (password == (iCharCombination)
    // return password found
    i++; // increment i by one
    }

    This is a very simplified pseudocode of the algorithm and possibly also wrong considering I just woke up and wrote it in a haste.
    Either way.. Just the iCharCombination has a time complexity of n!
    So I'd say the time complexity of this bruteforce is O(N!) if not O(N*(N!)) which is sick considering the amount of atoms in the universe is less than 78! if I remember correctly xD .. damn I should've paid more attention in class.

    Either way, if you want some proper facts I suggest you to ignore most of my words and just read yourself as I'm bit rusty in the subject.
    http://en.wikipedia.org/wiki/Time_complexity
    Look up Factorial time, Solving the traveling salesman problem via brute-force search

    Quick edit..
    There's better ways of cracking the password eg. password dictionaries instead of pure bruteforce. It's a dictionary (basically a list) of common used passwords, the crack will then go through and try all of these passwords to see if one of them is the right one.
