  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. 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 ...

    Create a strong password. • Use unique words - Don't use obvious words like "password". • Have 12 or more characters - Longer passwords are more secure. • Avoid sequences or repeated characters - Don't use adjacent characters on your keyboard (QWERTY). • Use a different password for each site - Otherwise, if someone acquires one ...

  5. bcrypt - Wikipedia

    en.wikipedia.org/wiki/Bcrypt

    Description. The input to the bcrypt function is the password string (up to 72 bytes), a numeric cost, and a 16-byte (128-bit) salt value. The salt is typically a random value. The bcrypt function uses these inputs to compute a 24-byte (192-bit) hash. The final output of the bcrypt function is a string of the form:

  6. Secure Hash Algorithms - Wikipedia

    en.wikipedia.org/wiki/Secure_Hash_Algorithms

    The Secure Hash Algorithms are a family of cryptographic hash functions published by the National Institute of Standards and Technology (NIST) as a U.S. Federal Information Processing Standard (FIPS), including: SHA-0: A retronym applied to the original version of the 160-bit hash function published in 1993 under the name "SHA".

  7. Password cracking - Wikipedia

    en.wikipedia.org/wiki/Password_length_equation

    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 ...

  8. Password - Wikipedia

    en.wikipedia.org/wiki/Password

    Password. A password, sometimes called a passcode, is secret data, typically a string of characters, usually used to confirm a user's identity. Traditionally, passwords were expected to be memorized, [1] but the large number of password-protected services that a typical individual accesses can make memorization of unique passwords for each ...

  9. Cognitive password - Wikipedia

    en.wikipedia.org/wiki/Cognitive_password

    Cognitive password systems have been researched for many years and are currently commonly used as a form of secondary access. They were developed to overcome the common memorability vs. strength problem that exists with the traditional password. Cognitive passwords, when compared to other password systems, can be measured through the usage of a ...
