Ophcrack is a Windows password cracker based on a time-memory trade-off using rainbow tables. This is a new variant of Hellman's original trade-off, with better performance. It recovers 99.9% of alphanumeric passwords in seconds.
- Cracks LM and NTLM Windows hashes
- Free tables available for Windows XP, Vista and 7
- Brute-force module for simple passwords
- Audit mode and CSV export
- Real-time graphs to analyze the passwords
- LiveCD available to simplify the cracking
- Loads hashes from encrypted SAM recovered from a Windows partition
While I've used previous versions of Ophcrack with success on XP, the Ophcrack 3.6 live disk failed to crack passwords for Windows 7 Professional. I also installed the 64 bit version, then selected and downloaded the available Vista tables (since no free Windows 7 tables were available), and it also failed to crack passwords on Windows 7 Pro.

I burned the LiveCD to USB with Rufus, but my computer always says that the boot drive failed. I am trying to get into a Windows 8 machine.
I click on "Crack" and nothing happens.
I created 3 different bootable USB sticks - using "tazusb.exe" - 4GB, 8GB and 16GB. I also added it to my YUMI USB stick which has lots of .ISOs on it that all work. None of them booted ophcrack. Two of them just displayed one line... something about Linux and a name like "Aaron", and one of them just showed a blinking cursor at the top of a blank screen. I tried all of them on a Netbook and my new Desktop. Total failure. I also burnt a CD. It didn't boot either. Fortunately, I read someone else's comment about "Hiren's Boot CD" (thank you, "dahoppsrno1"!). That has a utility on it to clear passwords and it works.
