553304 2007-05-26 06:54:00 My brother is sending me a zip file (just a text) which he password protected with winzip 11.1 256bit encrypt. He wants to see if I can crack it. So, how the hell do I? Preferably without downloading anything, or blowing my computer up, how do I crack it?

Windows XP SP2.

Thanks.

Have a very good guess. Pay him unless you can read the text.
I was also under the impression that this sort of subject was not allowed in this forum.

553305 2007-05-26 06:59:00 ^I was just wondering if it was possible. --Wolf-- (128)
553306 2007-05-26 07:04:00 So in other words, it's impossible?

nah just very hard, you could probably pick up a password cracking app on the web, I gather there are a few around.

553307 2007-05-26 08:52:00 Well I didn't bet it...it was more of a "I'll give you $20 if you can"

I've got to the end of 2007...but it sounds like I won't crack it.

It's only a txt document inside the zip folder...is there a way to see what's in the txt? I only need to tell him what it says to win.

hex editor























maybe

553309 2007-05-26 09:25:00 Send it to me and we can split the 20 if I open it. :D Greg (193)

Depends on how fast the machine is that is cracking it.

Unless you rigged your PC up to an Xbox grid cluster running Linux ;)

I'll give you the whole 20 if you can crack it. I just really want to prove him wrong. He's so damn confident that I'll never open it.
