This method is useful for cracking passwords that do not appear in dictionary wordlists, but it takes a long time to run. John uses character frequency tables to try plaintexts containing more frequently used characters first. In this type of attack, the program goes through all the possible plaintexts, hashing each one and then comparing it to the input hash. Many of these alterations are also used in John's single attack mode, which modifies an associated plaintext (such as a username with an encrypted password) and checks the variations against the hashes. It can also perform a variety of alterations to the dictionary words and try these. It takes text string samples (usually from a file, called a wordlist, containing words found in a dictionary or real passwords cracked before), encrypting it in the same format as the password being examined (including both the encryption algorithm and key), and comparing the output to the encrypted string.

One of the modes John can use is the dictionary attack.
