If we know the likely character set the target is using for their password, we can select the character set to generate our password list. One of the beauties of crunch is the ability to select a specific character set or create your own character set for generating your password list. Step 5: Complex Wordlists with Crunch The sign is use to represent a wildcard of all possibilities, while the literals "0728" represent the fixed values. Kali > crunch 10 10 -t -o /root/birthdaywordlist.lst If we knew that the target's birthday was July 28 and they likely used that date (people often use their birthdates in their passwords to make it easier to remember) at the end of a ten character password? We could generate all the possibilities of ten-character passwords that end with 0728 and send the output to a file in the root user's directory named birthdaywordlist.lst, by typing: Kali>crunch 6 8 1234567890 -o /root/numericwordlist.lst What if we knew that the target always used number passwords between 6 and 8 characters? We could generate a complete list of password possibilities meeting this criteria and send them to a file in the root user's directory called numericwordlist.lst by typing:
When we execute this statement, crunch estimates how large the file will be (1812 GB) and then begins to generate the list. Where the first number (4) is the shortest word length and the second (8) is the longest word length. We can generate all the possibilities in crunch by typing: Let's assume that we know the company has passwords between 4 and 8 characters. Let's start by generating some simple wordlists for password cracking.

Here we tell crunch where the charset.lst is with the full path and then select a particular character set from that list. This switch allows us to choose the character set we want to use to generate our wordlist. If we page down a bit in these man pages, we will come to this page (notice at the bottom, it says we are at line 70).Īt the top we see the -f switch.

The developers of crunch have packed these pages with a lot of info on how to get the most out of crunch.
#John the ripper wordlist manual
This should open the manual pages for crunch like that below.
Let's go to the man pages for crunch by typing: o = This is the file you want your wordlist written to. For instance, if you knew that the target's birthday was 0728 (July 28th) and you suspected they used their birthday in their password (people often do), you could generate a password list that ended with 0728 by giving crunch the pattern This word generate passwords up to 11 characters (7 variable and 4 fixed) long that all ended with 0728. t = The specified pattern of the generated passwords. Now, let's go over what's included in the syntax above.Ĭharacterset = The character set to be used in generating the passwords.
The basic syntax for crunch looks like this: I believe that's because crunch, although relatively simple to work with initially, has so many sophisticated options that the developer has put much of the information in man pages. Unlike many other hacking applications, crunch doesn't provide us with much info in its opening screen. This will open the crunch screen like that below.

Let's start by firing up Kali and opening crunch by going to Applications -> Kali Linux -> Password Attacks -> Offline Attacks -> crunch. Let's get started with crunch and generate some custom wordlists to crack passwords in our favorite password cracking tool. This custom wordlist might be able to save us hours or days in password cracking if we can craft it properly.
Kali Linux has built into it a tool called "crunch" that enables us to create a custom password-cracking wordlist that we can use with such tools like Hashcat, Cain and Abel, John the Ripper, Aircrack-ng, and others. In these cases, we may be able to generate a custom wordlist that reflects our knowledge of the target or the organization's password policy. minimum 8 characters, uppercase and lowercase, etc.). We may also know the organization's password policy (e.g. It could be their name, children's names, a pet's name, birthday, or job. Sometimes we may have indications of the target's choice password or password components which may come from our knowledge of the target, e.g. These wordlists may have any combination of characters and words in an attempt to crack a complex password offline. This is often referred to as a dictionary attack, even though we need not rely solely on dictionary words. In many of our password cracking disciplines, we often need to use a wordlist that will essentially attempt thousands of potential passwords per second. Although it might seem like a simple and straightforward exercise, those of you who have attempted password cracking know that there are many subtleties to this art. In this series on password cracking, I have been attempting to develop your skills in the age-old art of password cracking.
