 Password cracking - Wikipedia, the free encyclopedia   (Site not responding. Last check: 2007-11-01)
Password cracking is the process of recovering secret passwords from data that has been stored in or transmitted by a computer system, typically, by repeatedly verifying guesses for the password.
Passwords to access computer systems are usually stored, in some form, in a database in order for the system to perform password verification.
Even though functions that create hashed passwords may be cryptographically secure, possession of a hashed password provides a quick way to verify guesses for the password by applying the function to each guess, and comparing the result to the verification data.

 Password cracking   (Site not responding. Last check: 2007-11-01)
The purpose of password cracking might to help a user recover a forgotten (though installing an entirely new password is of a security risk) to gain unauthorized to a system or as a preventive by the system administrator to check for crackable passwords.
Passwords to access computer systems are usually in an encrypted or hashed form in a central database along the user name and system wide security for a specific user (such as the home directory intial configuration preferences etc).
When the attacker has several encrypted passwords crack rather than just one it is to improve the efficiency of the dictionary Since encrypting a word takes much longer comparing it with a stored word a of effort is saved by encrypting each only once and comparing it with each the encrypted passwords one by one.

 Password cracking - InformationBlast
The purpose of password cracking might be to help a user remember a forgotten password, to gain unauthorized access to a system, or as a preventive measure by the system administrator to check for easily crackable passwords.
Passwords to access computer systems are usually stored in an encrypted or hashed form in a central database, along with the user name and system wide security policies for a specific user (such as the user's home directory).
However, these methods are usually not considered to constitute password cracking; the term is used to refer to recovering the plaintext password from the encrypted or encoded version.

 Password   (Site not responding. Last check: 2007-11-01)
Password use is often depicted in fiction, Illya Kuryakin 'proving' his identity to the U.N.C.L.E. security door with a code word, or Harry Potter giving a password to a magic painting to enter his dormitory.
A password might be guessable if a user chooses an easily-discovered piece of personal information as a password (such as a student ID number, a boy- or girlfriend's name, a birthday, a telephone number, or a license plate number).
A weak password would be one that was short or was a default, or which could be rapidly guessed by searching a subset of all possible passwords such as words in the dictionary, proper names, words based on the user name or common variations on these themes.

 Russian Password Crackers: Password Cracking FAQ
If they fail, the password is not so simple, and it's a good idea to switch to the key-searching procedure (see 2.4).
The second method is insecure and can be cracked instantly, the first one is better, but key length is 40 bit that also results in success of key-searching procedure.
For example, the library that allows you to write the password cracker with built-in "rule-based attack" (see 1.4) is Password Cracking Library.

 Introduction to password cracking on Xatrix Security
Password cracking is a term used to describe the penetration of a network, system, or resource with or without the use of tools to unlock a resource that has been secured with a password.
In this article I will take a look at what password cracking is, why attackers do it, how they achieve their goals, and what you can do to do to protect yourself.
Because the majority of passwords are often simplistic, running a dictionary attack is often sufficient to to the job.

 SecuriTeam™ - Patch Available for the Syskey Keystream Reuse Vulnerability
Syskey is a utility that strongly encrypts the hashed password information in the SAM database in order to protect it against offline password cracking attacks (for example, the l0phtcrack cracking tool).
Password cracking is a means by which a malicious user tries to determine another user's password.
Offline password cracking is used if the strength of the cryptographic protection too high to allow the attacker to crack the password in real time.

 Password cracking   (Site not responding. Last check: 2007-11-01)
Passwords to access computer systems are usually stored in an encrypted or hashed form in a central database, along with the user name and system wide security policies for a specific user (such as the user's home directory, initial configuration preferences, etc).
There are many ways of obtaining passwords illicitly, such as social engineering, wiretapping, keystroke logging, login spoofing, dumpster diving, phishing, shoulder surfing, timing attack, acoustic cryptanalysis and compromising host security (see password for details).
A last resort is to try every possible password, known as a brute force attack.

Passwords must be known to the authenticating server and nobody else (save the user, of course).
Password encryption is done using a one-way hashing algorithm, meaning that as far as we know, there is no way to look at the hash and calculate what password was used to make it.

Ovviamente la possibilità di cracking delle password non si riduce a zero anche seguendo queste poche regole, che oltretutto pur semplici sono spesso ignorate, ma di sicuro rendono difficoltosi tutti quegli attacchi al proprio sistema che mirano al cracking di una password.

I have worked for many large (in terms of user base) companies and the biggest problem is to first explain how to create a complex password and the second is to get them to remember it.

 UNIX SECURITY - Understanding Password Cracking
The computer stores the password encrypted with a hash function; when we type in a password, the computer encrypts it with the same hash function and compares the results.
If your password is any word out of a dictionary -- even a foreign dictionary -- or a common word that has been modified in a simple way (such as by adding a period or numeral at the end), then the chances are that a dictionary attack can break it in a matter of seconds.
Similarly, a password made up of personal information (such as a birth date, a pet's name, or a favorite sports team) can be easily discovered, added to a word list, and used in a dictionary attack.
