This document explains the rtgen and rtsort programs. Rainbow tables are ordinary files stored on hard disk. The RainbowCrack software cracks hashes by rainbow table lookup. You can go through the manual and check out the other available options.Rainbow Table Generation and Sort Introduction This will generate all the 8-character passwords using the lower alphabetic and number characters. Now, if we know that our target is using an eight character password with only alphabetic characters, we can generate a list of all the possibilities in crunch with the command:Ĭrunch 8 8 -f /usr/share/rainbowcrack/charset.txt loweralpha-numeric -o /root/loweralphanumeric.lst We can find the choice of character sets at: 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. If we knew that the target has a password of 8 characters and ends with 1&2 we can use the following command: 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 these criteria and send them to a file in the root user’s directory called number8.lst by typing:Ĭrunch 6 8 1234567890 -o /root/numericwordlist.lst When we execute this statement, crunch estimates how large the file will be (1463 TB) and then begins to generate the list. To create simple wordlists type crunch max -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.characterset= The character set to be used in generating the passwords.Now, let’s go over what’s included in the syntax above. The basic syntax for crunch looks like this: To view the manual of crunch and options available, you can use the command man crunch. Start your Kali Linux, open the terminal, and type crunch to see if the crunch is installed, and whether or not it’s the most current version.
