SPass: Simple & Secure Passwords

Generate secure passphrases to use instead of random strings! (Random strings are also an option)

Do you want cryptographically strong passwords for your applications/accounts/anything you want? Then never fear as SPass is here! SPass leverages the built in secrets library and over 7776 words to randomly generate passphrases or even passwords. It even calculates the entropy for you.**

**It calculates the entropy of passwords, however at this point in time it only calculates the minimum entropy of passphrases as well as a deviation. So for passphrases the true value is (entropy +- deviation)

How to use

Try generating passwords:

import spass
spass.generate_passphrase()
# Will output something like:
# {'password': 'movieChipcorrectvertigomany', 'entropy': 69.62406251802891, 'deviation': 0.0}

You can even add a bit of padding to it:

import spass
spass.generate_passphrase(pad_length=2)
# {'password': 'poroustrimester#landslide4UneditedSlacking', 'entropy': 69.62406251802891, 'deviation': 10.784634845557521}

spass.generate_passphrase(pad_length=2, punctuation=False)
# {'password': '4undrilleddilationfifteenGloater7Wager', 'entropy': 69.62406251802891, 'deviation': 6.643856189774725}

You can specify exactly what symbols you don't want in your padding:

import spass
spass.generate_passphrase(pad_length=5, ignored_symbols=',./;:\'\"\\|[]{}()')
# The generated passphrase will not have any of the characters you ignored in the padding
# {'password': 'Unnamed<>`retract#Tighten-exemptionstitch', 'entropy': 69.62406251802891, 'deviation': 23.774437510817343}

Or be old fashioned and go with a very secure random password:

import spass
spass.generate_random_password(length=20)
# {'password': "uOp/J:2Mejvz#-v`h'?1", 'entropy': 131.09177703355275}

spass.generate_random_password(length=20, punctuation=False)
# You can turn off digits, punctuation or even letters
# {'password': 'GNLbfgCOehmeZXXHUf6E', 'entropy': 119.08392620773752}

spass.generate_random_password(length=20, ignored_chars='\'\":;<>,./?[]{}\\()')
# Or just ignore specific symbols
# {'password': 'rLr3oku%J7a|*y28SjHv', 'entropy': 125.33573081389804}

Installation

Just use pip:

pip3 install spass

Currently SPass is designed to only work with Python 3.6+. It will not be compatible with Python 2.

Contribution

This is my first open source project and I'm really putting myself out in the wild for the sake of learning. I appreciate all feedback and any contributions to improve this package. Thanks!
