A simple rainbow table generator
A simple rainbow table generator written in Python 3.
Leprechaun.py is a simple Python program used for generating cryptographic rainbow tables. This script can compute hashes using the MD5, SHA1, SHA256 and SHA512 algorithms. Leprechaun can hash any arbitrary number of plaintext files, as long as they’re within the same directory. Or, if you’re a normal person without a huge directory filled with wordlists, you can hash one single file. The choice is yours!
Leprechaun is available for download from PyPI using pip, just like everything else!
$ mkdir DIRECTORY $ cd DIRECTORY $ virtualenv -p python3 . $ pip install leprechaun
leprechaun [-h] [-g] [-l LENGTH] [-d] [-o OUTPUT] [-m] [-s] [-s2] [-s5] WORDLIST
(Positional Arguments) WORDLIST The file name of the wordlist to hash, without the file extension (Optional Arguments) -h, --help Show this help message and exit (Wordlist Arguments) -f, --wordlist-folder Hash all of the plaintext files in a folder, rather than a single file. The name of the folder will be set by the WORDLIST argument -g, --generate-wordlist Generate a wordlist dynamically instead of using a pre-built one; the name of the dynamically generated wordlist will be set by the WORDLIST argument -l LENGTH, --word-length LENGTH The maximum length of the words to be generated (default=8) (Output Arguments) -o OUTPUT, --output OUTPUT Name of the rainbow table file, without the file extension (default=rainbow) -d, --use-database Save the output to an SQLite DB instead of a plaintext file (Hashing Arguments) -m, --md5 Generate MD5 hashes of given passwords (default) -s, --sha1 Generate SHA1 hashes of given passwords -s2, --sha256 Generate SHA256 hashes of given passwords -s5, --sha512 Generate SHA512 hashes of given passwords
Below are a few simple examples on using Leprechaun.py. While not an exaustive compilation of use cases, the program itself is quite simple to figure out on one’s own.
# Create a rainbow table using the MD5 hashing algorithm. leprechaun /path/to/your/wordlist.txt # Create a rainbow table using the SHA-1 hashing algorithm. leprechaun -s /path/to/your/wordlist.txt # Create a rainbow table using the SHA-1 hashing algorithm, saving the # output in an SQLite database. leprechaun -s -d /path/to/your/wordlist.txt # Create a rainbow table using the SHA-256 hashing algorithm, hashing all of # the plaintext files in a given directory, saving the output in an SQLite # database. leprechaun -s2 -d -f /path/to/your/wordlists # Create a rainbow table using the SHA-256 hashing algorithm, hashing all of # the plaintext files in a given directory, saving the output in an SQLite # database named "patty" leprechaun -s2 -d -o patty -f /path/to/your/wordlists
Because any good wordlist contains several million lines of words, and several million lines of anything takes up a heck of a lot of space, the previously distributed wordlist is no longer being distributed. But don’t fret! I’ve uploaded that same wordlist onto the Internet for everyone to enjoy. You may find it here.
