2. Password strength - Wikipedia

   en.wikipedia.org/wiki/Password_strength

   Password strength. Options menu of the random password generation tool in KeePass. Enabling more character subsets raises the strength of generated passwords a small amount, whereas increasing their length raises the strength a large amount. Password strength is a measure of the effectiveness of a password against guessing or brute-force attacks.

3. Password cracking - Wikipedia

   en.wikipedia.org/wiki/Password_cracking

   Password cracking. 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 in scrambled form. A common approach ( brute-force attack) is to repeatedly try guesses for the password and to check them against an available ...

4. Brute-force attack - Wikipedia

   en.wikipedia.org/wiki/Brute-force_attack

   Brute-force attacks work by calculating every possible combination that could make up a password and testing it to see if it is the correct password. As the password's length increases, the amount of time, on average, to find the correct password increases exponentially. Theoretical limits

5. Wikipedia:10,000 most common passwords - Wikipedia

   About. If your password is on this list of 10,000 most common passwords, you need a new password. A hacker can use or generate files like this, which may readily be compiled from breaches of sites such as Ashley Madison. Usually passwords are not tried one-by-one against a system's secure server online; instead a hacker might manage to gain ...

6. Key stretching - Wikipedia

   en.wikipedia.org/wiki/Key_stretching

   Key stretching. In cryptography, key stretching techniques are used to make a possibly weak key, typically a password or passphrase, more secure against a brute-force attack by increasing the resources (time and possibly space) it takes to test each possible key. Passwords or passphrases created by humans are often short or predictable enough ...

7. L0phtCrack - Wikipedia

   en.wikipedia.org/wiki/L0phtCrack

   L0phtCrack. L0phtCrack is a password auditing and recovery application originally produced by Mudge from L0pht Heavy Industries. It is used to test password strength and sometimes to recover lost Microsoft Windows passwords, by using dictionary, brute-force, hybrid attacks, and rainbow tables. [3] The initial version was released in the Spring ...

8. Crack (password software) - Wikipedia

   en.wikipedia.org/wiki/Crack_(password_software)

   Crack is a Unix password cracking program designed to allow system administrators to locate users who may have weak passwords vulnerable to a dictionary attack.Crack was the first standalone password cracker for Unix systems and the first to introduce programmable dictionary generation as well.

9. Data Encryption Standard - Wikipedia

   en.wikipedia.org/wiki/Data_Encryption_Standard

   As of 2008, the best analytical attack is linear cryptanalysis, which requires 2 43 known plaintexts and has a time complexity of 2 39–43 (Junod, 2001). The Data Encryption Standard ( DES / ˌdiːˌiːˈɛs, dɛz /) is a symmetric-key algorithm for the encryption of digital data. Although its short key length of 56 bits makes it too insecure ...
