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 ...
One weakness of PBKDF2 is that while its number of iterations can be adjusted to make it take an arbitrarily large amount of computing time, it can be implemented with a small circuit and very little RAM, which makes brute-force attacks using application-specific integrated circuits or graphics processing units relatively cheap.

More common methods of password cracking, such as dictionary attacks, pattern checking, and variations of common words, aim to optimize the number of guesses and are usually attempted before brute-force attacks. Higher password bit strength exponentially increases the number of candidate passwords that must be checked, on average, to recover ...
A brute-force algorithm that finds the divisors of a natural number n would enumerate all integers from 1 to n, and check whether each of them divides n without remainder. A brute-force approach for the eight queens puzzle would examine all possible arrangements of 8 pieces on the 64-square chessboard and for each arrangement, check whether ...
In addition, broken by brute force in 2 56 time, no later than 1998-07-17, see EFF DES cracker. [8] Cracking hardware is available for purchase since 2006. [9] Triple DES: 2 168: 2 113 time, 2 32 data, 2 88 memory; 64-bit block is vulnerable to SWEET32 attack. 2016 Extension of the meet-in-the-middle attack.
As mentioned in the Motivation section, SCRAM uses the PBKDF2 mechanism, which increases the strength against brute-force attacks, when a data leak has happened on the server. Let H be the selected hash function, given by the name of the algorithm advertised by the server and chosen by the client. 'SCRAM-SHA-1' for instance, uses SHA-1 as hash ...
In cryptography, security level is a measure of the strength that a cryptographic primitive — such as a cipher or hash function — achieves. Security level is usually expressed as a number of "bits of security" (also security strength), [1] where n-bit security means that the attacker would have to perform 2 n operations to break it, [2] but other methods have been proposed that more ...
