| 553315 | 2007-05-26 10:38:00 | You know you can rent processing time on the massive Linux server farm that Weta initially built in Wellington? Although I don't think $20 would get you many CPU cycles. :D | Jen (38) | ||
| 553316 | 2007-05-26 14:51:00 | Um, 256 bit is not even that hard IF you have lots of access to lots of computer time, scientists, technicians and good algorithms: www.pcworld.com actualites.epfl.ch |

| 553317 | 2007-05-27 03:43:00 | Seriously, no home user would be able to do it, no matter how many xbox's, pc's, or whatever borrowed from their friends and linked together. It's just not going to happen. | mejobloggs (264) | ||
| 553318 | 2007-05-27 03:54:00 | A brute force password cracker would open the file. Eventually. Be prepared for a very long wait. It doesn't take many characters in a password for the potential time required to approach the lifetime of the universe. Of course if you have access to the NSA backdoor ... :D | Graham L (2) | ||
| 553319 | 2007-05-27 04:52:00 | A brute force password cracker would open the file. Eventually. Be prepared for a very long wait. It doesn't take many characters in a password for the potential time required to approach the lifetime of the universe. Of course if you have access to the NSA backdoor ... :D Yes - I have cracked one before (it was mine and I forgot the password). Cracking say, a 6 letter password takes just a minute or so on my PC, but you need to realise that a 7 letter password takes 36 times as long (36 min) if you use only letters and numbers, so an 8 letter password takes 1296 times as long (21 hours), and a 9 letter password takes over 32 days. If it's longer than that you're completely wasting your time. Brute force is the only way you could crack it. |

| 553320 | 2007-05-27 04:55:00 | Upper and lower case makes it much worse, George. ;) Try 52x worse for each extra character. | Graham L (2) | ||
| 553321 | 2007-05-27 05:08:00 | And symbols. :rolleyes: | Erayd (23) | ||
| 553322 | 2007-05-27 07:34:00 | He told me the password is only 5 numbers...That information halved the bet though, so now if I get it, I only get $10. Will try and look for a brute cracker thingy. |

| 553323 | 2007-05-27 10:06:00 | You'll need to subject the file to a brute-force password cracker. There is software, Google 'Brute Force password decrypt' or something to that effect. Problem is once you get past about 3 character passwords you could be waiting 6 months for the correct password to be determined. That's of course if you leave your 'puter on 24/7 (hope it's not in your bedroom as they're awful noisy sometimes) and devote all of the processor power. But wait there's more....it could take even longer is symbols as well as the alphabet and numbers are in the password. I would charge $20.00 just thinking about it, let alone doing anything. |
