Take you to know the password "breaking" software under Linux

When using a computer, it often interacts with some encrypted documents, such as Zip, Rar, and even PDF documents.

Sometimes we forget the password of the document and we have to use the "brute force" method. So is there any related software under Linux?

Of course, this article introduces three brute force software under Linux.

The Linux environment uses Ubuntu 7.10 as an example. The following three softwares are included in the Ubuntu source and can be installed directly by apt-get install.

1, crack Zip file password

Now the most popular document format on the network is zip, so first introduce this crack ZIP file password software, it is the name is fcrackzip, based on the command Row.

Fcrackzip has the main functions of general cracking software, which is divided into exhaustive cracking and dictionary cracking. If you know the number of characters or characters of a password, then it is most appropriate to use an exhaustive crack.

It also has a test function that lets you know the speed of native cracking.

For example, if you know that a Zip file consists of 6 lowercase letters, just run:

fcrackzip -ca -p aaaaaa sample.zip

fcrackzip Will exhaust all possibilities from aaaaaa to zzzzzz, and soon the password will be cracked.

Other methods of use can be found in fcrackzip –help

2, crack PDF documents

In order to protect private documents, PDF encryption is also more and more. With another software: pdfcrack, you can crack PDF documents. It is also a command-line software that supports cracking all known PDF versions.

Similar to fcrackzip, pdfcrack has exhaustive, dictionary and basic testing capabilities. Although the command line parameters are not the same, they are basically similar.

In the simplest case, you don't have to specify any parameters, just “pdfcrack filename”

3, crack the Windows password

Although this has nothing to do with cracking the document password, but it is indeed Linux can do: crack the password of Windows NT/2000/XP/Vista!

Cracking Windows passwords with ophcrack's GTK+-based graphics software is not a difficult task, including cracking the latest Vista.

More powerfully, using Ophcrack LiveCD: Ophcrack LiveCD, you can take the CD, where to go, where to crack: the CD has the ability to load encrypted SAM from the Windows partition, and No need to install, start with the CD to start cracking.

You can learn more from Ophcrack and install it directly under Ubuntu.

This article only describes the Linux system more vice of software, we can see that Linux software is also very rich, of course, but most are not graphics software And already
