The Fastest Windows Password Cracker

**Jared Moya** · January 8th, 2007, 04:18 PM

Ophcrack is a Windows password cracker based on rainbow tables. It is a very efficient implementation of rainbow tables done by the inventors of the method.

I am going to guess they are combinations of characters that are set up in a table and to crack the password they get placed in until they crack the password. As for the use, maybe if a senior tech got fired and was pissed off and switched a password on an encrypted important machine and the only way to keep the files would be to crack into windows.

Ha, rainbow tables are files containing all possible password in hash format.

Ilove rcrack, but my tables take up nearly 1TB on me server

all info can be found at http://www.antsight.com/zsl/rainbowcrack/
and a project from sourceforge.net http://rainserv.sourceforge.net/

I think I'll get some cereal too.

it works,i have tried it myself,but if the password is really big with symbols etc then the hashs required are too large making it difficult to crack from a cd or a DVD.

It could be a useful tool in the proper hands. I recall another hash cracker called rockxp which has some useful features.

I recall a problem I once had, where I had encrypted files on a partition and I foolishly formatted windows on C: partition. I am not aware of any software that can unencrypt your files after doing so. From what I remember it would have been quite complicated to retrieve them.

Very interesting. I was going to try it, but why crack my own passwords.....

**Mels_Smileys45** · April 21st, 2007, 09:03 PM

I guess this is good idea if you want to get into some ones pc with out them knowing. Or you could just run erd commander from cd and change the admin password.
