  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

    A brute-force attack is a cryptanalytic attack that can, in theory, be used to attempt to decrypt any encrypted data (except for data encrypted in an information-theoretically secure manner). [1] Such an attack might be used when it is not possible to take advantage of other weaknesses in an encryption system (if any exist) that would make the ...

    en.wikipedia.org/wiki/John_the_Ripper

    John the Ripper. John the Ripper is a free password cracking software tool. [3] Originally developed for the Unix operating system, it can run on fifteen different platforms (eleven of which are architecture-specific versions of Unix, DOS, Win32, BeOS, and OpenVMS ). It is among the most frequently used password testing and breaking programs [4 ...

  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. Password fatigue - Wikipedia

    en.wikipedia.org/wiki/Password_fatigue

    Third-party (add-on) password management software such as KeePass and Password Safe can help mitigate the problem of password fatigue by storing passwords in a database encrypted with a single password. However, this presents problems similar to that of single sign-on in that losing the single password prevents access to all the other passwords ...

  9. Hydra (software) - Wikipedia

    en.wikipedia.org/wiki/Hydra_(software)

    Hydra works by using different approaches to perform brute-force attacks in order to guess the right username and password combination. Hydra is commonly used by penetration testers together with a set of programmes like crunch, cupp etc, which are used to generate wordlists. Hydra is then used to test the attacks using the wordlists that these ...
