One of the modes John can use is the dictionary attack. [6] 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.
words is a standard file on Unix and Unix-like operating systems, and is simply a newline-delimited list of dictionary words. It is used, for instance, by spell-checking programs. [1] The words file is usually stored in /usr/share/dict/words or /usr/dict/words.
Cain and Abel (often abbreviated to Cain) was a password recovery tool for Microsoft Windows.It could recover many kinds of passwords using methods such as network packet sniffing, cracking various password hashes by using methods such as dictionary attacks, brute force and cryptanalysis attacks.

A hacker can use or generate files like this, which may be readily compiled from breaches of sites such as Ashley Madison. Usually, passwords are not tried one-by-one against a system's secure server online; instead, a hacker might manage to gain access to a shadowed password file protected by a one-way encryption algorithm.

will compile a Unicode-compatible DICT file called mydict, with heading My Dictionary, from mydict.txt which is in Jargon File format i.e.: :word1:definition 1 :word2:definition 2 etc. Once the dictionary file has been produced, it can be easily installed on a server with commands similar to this:
Before starting a download of a large file, check the storage device to ensure its file system can support files of such a large size, check the amount of free space to ensure that it can hold the downloaded file, and make sure the device(s) you'll use the storage with are able to read your chosen file system.
It is similar to a password in usage, but a passphrase is generally longer for added security. Passphrases are often used to control both access to, and the operation of, cryptographic programs and systems, especially those that derive an encryption key from a passphrase. The origin of the term is by analogy with password. The modern concept of ...
