Request-WinRAR/Zip password cracker

[deth]

My sister got a little mad at me and decided it was fair to encrypt some files i was working on w/ winrar. :roll: so if anybody has/knows of any free programs, it'd be much appreciated

All the ones I tried didnt work very well.

damn..thats not too encouraging....would you mind tellingme which ones you tried and where you got them from? i'd just like to try them incase its an easy pass to crack

I did a quick search and found somethings, rar password cracker and winrar password cracker, but they seem to do brute force and dictionary attacks, these can take a while so you should have a pretty fast machine....
I am trying to get them off p2p, will pm you when I get it

[Jabba]

Well it was a while back...I got them off some crack/hacking site...they all seem to use a "brute force" method which not only takes forever but the actual chances of working seems to be ZERO.

[v0od0o]

brute force methods should work with passes up to 8 characters.... anymore and it's not feasible, at least on today's hardware
So it all depends now on how old your sister is

Well I tried putting on some basic passwords likes hamburger and they never got even close.

I will have to try them on my new 4.02 GHZ machine to see if I have any better luck.

[v0od0o]

hehehe, who uses hamburger as a password ?

[Jabba]

For a test...I did.

[v0od0o]

i was j/k
anyway brute-force attack is just about guessing all possible combinations of characters, so the time it takes is directly proportional to the length of the pass.
For example the software tries: a, b, c, d, .....etc
then aa, ab, ac, ad, ......etc
So for a brute force attack, hamburger (9 chars) is a strong password

[Jabba]

I think the one I was using was a dictionary attack....not sure if hamburger was in that dictionary though.
