"A dedicated fast Windows password cracker"
Written By

The freeware security utility offered here as a download is called Ophcrack. It’s an open-source Windows password cracker capable of revealing most passwords in a matter of minutes.

Without going into technical explanations about the techniques Ophcrack works with, we can mention it uses LM hashes via rainbow tables. This method significantly speeds up the cracking process and a dedicated set of such rainbow tables, optimised for this program, is available for free as well.

Note that this version includes support for cracking NTLM hashes as well, required for passwords that are longer than 14 characters or because LM hash generation is disabled, the latter being the default on some Windows operating systems.

So, if interested in this security application, proceed to the free download to add it to your toolkit right now.
