Create passphrases based on a input file

Phrases generator

How can we create password candidates for passphrases?
Well, we can scrape Twitter to harvest some slang words, but what if the user was using quotes from a text (a book or a movie)?
For example, what if the user chose a password like this:
godcreatedtheheaven

20 chars are simply too many for a brute-force attempt. What if we start to create phrases containing N words, based on a specific text?
For example, using a wordlist based on the Bible and with phrases containing from 4 to 7 words lead to these craked passwords:

25 withhisstripeswearehealed
23 amnotashamedofthegospel
22 rejoiceinthelordalways
21 wonderswithoutnumbers
20 theearthisthelords11
20 lordofheavenandearth
20 fearnotiwillhelpthee
20 andthewordwaswithgod
19 onehourwiththebeast
19 hardennotyourhearts

Requirements

No external libraries are required.

Usage

python phrases.py [OPTIONS] original_file.txt
The script will start to crawl the original text and output phrases with the selected amount of words, one per line.
For example, running the following command on the Bible, will produce something like this:

python phrases.py -w 4 -o bible4words.txt bible.txt

In the beginning God
the beginning God created

God created the heaven
created the heaven and

From this base text, you can tweak the final output using Hashcat rules.
