Brute-force attack

> In [[cryptography]], a brute-force attack consists of an attacker > submitting many passwords or passphrases with the hope of eventually guessing > correctly. The attacker systematically checks all possible passwords and > passphrases until the correct one is found. Alternatively, the attacker can > attempt to guess the key which is typically created from the password using a > key derivation function. This is known as an exhaustive key search.\ > — [Wikipedia](https://en.wikipedia.org/wiki/Brute-force_attack)
