Cryptanalysis Attack
In a cryptanalysis attack, an attacker compares a precomputed encrypted password to a value in a lookup table in order to try to find a match.
Warning!
There are a few ways to avoid this type of attack. One is to use a strong encryption algorithm that is not susceptible to this type of attack. Another is to use salt when encrypting passwords, which will make it more difficult for an attacker to precompute encrypted passwords.
