Inspired by the 'Password Strength' comic by xkcd
Pass phrases are 5 words; adjective, noun, verb, adjective, noun. I find this pattern produces phrases which are easier to remember/visualise than 4 completely random words as recommended by the xkcd comic.
From the command line
$ ./pass_phrase.py

In your own scripts
There is no easy way to use it in your own scripts at the moment. But if you really must use it right this second in your own scripts then you can do:
>>> from pass_phrase import generate_wordlist, passphrase
>>> adjectives = generate_wordlist("adjectives.txt")
>>> nouns = generate_wordlist("nouns.txt")
>>> verbs = generate_wordlist("verbs.txt")
>>> passphrase(adjectives, nouns, verbs, " ")

The script expects 3 different word files, I've included examples of these in the repo:
- adjectives.txt
- nouns.txt
- verbs.txt
It will check for the existence of these files in the current directory or in ~/.pass-phrase/
If you want to use other files, or relocate them, use the command line options.
$ ./pass_phrase.py --adjectives="/usr/share/dict/adjectives" --nouns="/usr/share/dict/nouns" --verbs="/usr/share/dict/verbs"
Options:
-h, --help show this help message and exit
--adjectives=ADJECTIVES

--nouns=NOUNS List of valid nouns for passphrase
--verbs=VERBS List of valid verbs for passphrase
-s SEPARATOR, --separator=SEPARATOR
Separator to add between words
-n NUM, --num=NUM Number of passphrases to generate
--min=MIN_LENGTH Minimum length of a valid word to use in passphrase
--max=MAX_LENGTH Maximum length of a valid word to use in passphrase
--valid_chars=VALID_CHARS
Valid chars, using regexp style (e.g. '[a-z]')
-U, --uppercase Force passphrase into uppercase
-L, --lowercase Force passphrase into lowercase
-C, --capitalise, --capitalize
Force passphrase to capitalise each word
--l337 7#izz R3@l|j !$ 4941Nst 7#3 w#()|e 5P|R!7 0pH t#3
7#|N6.
--l337ish A l337 version which is easier to remember.
-V, --verbose Report various metrics for given options
Thanks to Steven Tobin and his version of the XKCD-password-generator, it inspired me to add some additional features to my own version. I've also used bits & pieces of the code from XKCD-password-generator here.
