Analysis of Password Cracking Methods & Applications John A. Chester The University of Akron Abstract -- This project examines the nature of password cracking and modern applications. Several applications for different platforms are studied. Different methods of cracking are explained, including dictionary attack, brute force, and rainbow tables. Password cracking across different mediums is examined. Hashing and how it affects password cracking is discussed. An implementation of two hash-based password cracking algorithms is developed, along with experimental results of their efficiency. I. Introduction Password cracking is the process of either guessing or recovering a password from stored locations or from a data transmission system [1]. -

Microsoft Word 2010
Microsoft Word 2010 Prepared by Dr.salma Sultan Salman 1 P a g e | 2 1 - The Desktop The Desktop is the main Windows 7 screen (see image below). It is the work area where dialog boxes, windows, icons, and menus appear. Like an office desk, the Windows 7 desktop contains items you can use to do your job. For instance, from your desktop, you can perform file-management tasks and run software applications. You can customize the appearance of the desktop to suit your preferences. Desktop Icons The Desktop is where you’ll find icons (small pictures) for many of your most frequently used programs. You’ll most likely see icons for Computer, Documents, Recycle Bin, and Internet Explorer. Computer – Allows you to see what drives are attached to your computer (for example, your local hard disk drive, your CD/DVD drives, any networked shared drives, and external drives, such as a USB flash drive). You can also view the files that are located on these drives. Documents – Supplies a ‘catch-all’ place for your personal files. Within here you can see your files, any shared files from other computer users and any music or pictures you may have stored. The Documents folder will sometimes be identified by your name instead of the word “Documents.” Recycle Bin – Stores any files you delete until you empty it. Internet Explorer – Contains Windows’ built in web browser that integrates with other Windows components (such as your folders and Documents). 2 P a g e | 3 On the other hand, you can also create and edit icons for your own use. -
How to Handle Rainbow Tables with External Memory
How to Handle Rainbow Tables with External Memory Gildas Avoine1;2;5, Xavier Carpent3, Barbara Kordy1;5, and Florent Tardif4;5 1 INSA Rennes, France 2 Institut Universitaire de France, France 3 University of California, Irvine, USA 4 University of Rennes 1, France 5 IRISA, UMR 6074, France [email protected] Abstract. A cryptanalytic time-memory trade-off is a technique that aims to reduce the time needed to perform an exhaustive search. Such a technique requires large-scale precomputation that is performed once for all and whose result is stored in a fast-access internal memory. When the considered cryptographic problem is overwhelmingly-sized, using an ex- ternal memory is eventually needed, though. In this paper, we consider the rainbow tables { the most widely spread version of time-memory trade-offs. The objective of our work is to analyze the relevance of storing the precomputed data on an external memory (SSD and HDD) possibly mingled with an internal one (RAM). We provide an analytical evalua- tion of the performance, followed by an experimental validation, and we state that using SSD or HDD is fully suited to practical cases, which are identified. Keywords: time memory trade-off, rainbow tables, external memory 1 Introduction A cryptanalytic time-memory trade-off (TMTO) is a technique introduced by Martin Hellman in 1980 [14] to reduce the time needed to perform an exhaustive search. The key-point of the technique resides in the precomputation of tables that are then used to speed up the attack itself. Given that the precomputation phase is much more expensive than an exhaustive search, a TMTO makes sense in a few scenarios, e.g., when the adversary has plenty of time for preparing the attack while she has a very little time to perform it, the adversary must repeat the attack many times, or the adversary is not powerful enough to carry out an exhaustive search but she can download precomputed tables. -

Password Cracker Tutorial
Password cracker tutorial In cryptanalysis and computer security, password cracking is the process of recovering passwords[1] from data that has been stored in or transmitted by a computer system. A common approach (brute-force attack) is to repeatedly try guesses for the password and to check them against an available cryptographic hash of the password.[2] The purpose of password cracking might be to help a user recover a forgotten password (installing an entirely new password is less of a security risk, but it involves System Administration privileges), to gain unauthorized access to a system, or to act as a preventive measure whereby system administrators check for easily crackable passwords. On a file-by-file basis, password cracking is utilized to gain access to digital evidence to which a judge has allowed access, when a particular file's permissions are restricted. Time needed for password searches The time to crack a password is related to bit strength (see password strength), which is a measure of the password's entropy, and the details of how the password is stored. Most methods of password cracking require the computer to produce many candidate passwords, each of which is checked. One example is brute-force cracking, in which a computer tries every possible key or password until it succeeds. With multiple processors, this time can be optimized through searching from the last possible group of symbols and the beginning at the same time, with other processors being placed to search through a designated selection of possible passwords.[3] More common methods of password cracking, such as dictionary attacks, pattern checking, word list substitution, etc.
