Make-Rainbow-Table

A simple rainbow table generator supporting MD5, SHA224, SHA256, SHA384, and SHA512, written in Python 2.7.

Usage

$ python make-rainbow-table.py [-h] [-d DATABASE] [-w WORDLIST] [-t HASHTYPE]

Arguments:

-h, --help                                                  show this help message and exit

-d DB_NAME, --db=DB_NAME, --database=DB_NAME                Database to fill with hashes. (default='rainbow.db')
                    
-w WORD_LIST_NAME, --wordlist=WORD_LIST_NAME                Wordlist to read from and hash. (default='linux.words')
                    
-t md5|sha224|sha256|sha384|sha512|all, --type=HASHTYPE     Type of hash to use. (default='all')

Examples

By default, the program will create a database called rainbow.db and use its local wordlist 'linux.words.' It will hash each word using all hash-types included in this program.

$ python make-rainbow-table.py

You can specify what you feel necessary, however.

$ python make-rainbow-table.py -d rainbow.db -w linux.words -t all

$ python make-rainbow-table.py -t md5

$ python make-rainbow-table.py -d rbdatabase.db -w mycustom.list -t sha256

If the specified database does not exist, then it will be created for you.

Using the Generated Rainbow Table

There are plenty of ways to use this table to your advantage. This is a quick and easy method for 'cracking' a hash:

Scenario: Let's say you have a database containing your Rainbow Table called rainbow.db. You want to use it to crack this MD5 hash:

176ec4bc8d9dd70dc0e745d6ce103eaa

Open your Rainbow Table with SQLite3:

$ sqlite3 rainbow.db 

Now query for the hash:

sqlite> SELECT * FROM rainbow WHERE hash='176ec4bc8d9dd70dc0e745d6ce103eaa';

Your screen should now display:

176ec4bc8d9dd70dc0e745d6ce103eaa|abundant

This means that 'abundant' was the word that was hashed. Congrats!

Note: Again, there are lots of ways this can be accomplished. This is just one of 'em. This process can easily be scripted, but the purpose of this project is to generate a Rainbow Table; not use it to crack hashes.
