What is Crunch?
Crunch is a wordlist generator where you can specify a standard character set or any set of characters to be used in generating the wordlists. The wordlists are created through combination and permutation of a set of characters. You can determine the amount of characters and list size.
This program supports numbers and symbols, upper and lower case characters separately and Unicode.
Cheatsheet
-b: specifies the maximum size of the wordlist.
-c: specifies the number of lines to write to the wordlist.
-d: limits the number of duplicate characters
-e: stop generating words at a certain string
-f: specifies a list of character sets from the charset.lst file
-i: inverts the order of characters in the wordlist
-l: allows the literal interpretation of %,@^ when using -t
-o: specifies the output wordlist file
-p: prints permutations without repeating characters.
-q: Like the -p option but it reads the strings from a specified file
-r: resumes a previous session (cannot be used with -s)
-s: specifies a particular string to begin the wordlist with
-t: sets a specific pattern of @,%^
-z: compresses the output wordlist file, accompanied by -o
@represents lowercase letters
^represents special characters
% represents numbers
, represents uppercase lettersExample of usage
To create a word list of specific numbers.
crunch 1 2 0123456789 > wordlist.txt
This command will generate a wordlist of 110 words having the one and 2 digit numbers with all combinations of digits 0, 1, 2, 3, 4, 5, 6, 7, 8, 9. you could use alphabets
To generate a wordlist with a specific pattern.
crunch 9 9 -t juve^%%%%Here we have 4 characters to represent some group of characters which are as follows:
, for all uppercase letters
@ for all lowercase letters
% for all numeric characters
^ for all special characters
So the above command will output all the words starting with “juve” and then after that a special character and then 4 digit number.
To generate a custom wordlist with letters, symbols and numbers.as
This Step is for Mixed with letters, Symbols, Numbers and creating a custom wordlist Run this command on Your terminal
crunch 4 8 123abcdefgh#$% -o list.txtcrunch <min> <max> <charset> -o <output in text file>
min : It is the minimum password length.
max : It is the maximum password length.
charset: Character se to be used.
-o : Output in a textfile. along with name of the text file.
To generate a wordlist with a permutation of some strings or characters
crunch 1 10 -p juve 123In the case of -p, the minimum size and the maximum size values are ignored by the crunch and it displays all the possible permutations.
The above command will give 2 permutations of “juve 123”.
