Test the strength of your password or generate a strong one. Rate your password or generate a strong one.

• Disclaimer:

This application is designed to assess the strength of password strings. And provides the user a means to improvethe strength of their passwords, with a hard focus on breaking the typical bad habits of faulty password formulation.

Since no official weighting system exists, we created our own formulas to assess the overall strength of a given password.

Please note, that this application does not utilize the typical "days-to-crack" approach for strength determination. We have found that particular system to be severely lacking and unreliable for real-world scenarios. This application is neither perfect nor foolproof, and should only be utilized as a loose guide in determining methods for improving the password creation process

Features:

• A simple to use API for testing the strength of your password.
• Generating strong passwords.

First install the dependencies with pip :

pip install -r requirements.txt

Usage example 1:

>>> from password_meter import Password
>>> password = Password('Azerty22')
>>> password.rate()

Usage example 2:

>>> from password_meter import Password
>>> from constants import *
>>> Password().find(8, spec=USE_PUNCTATIONS+USE_DIGITS)
# or this will return a new safe password and its score:
>>> my_password, my_score = Password().find(8, display=False)

TEST:

Code used for representation:

>>> from password_meter import Password
>>> from constants import *
>>> from matplotlib import pyplot as plt
>>> # find best password algorithm
>>> Password().find(12, spec=ALL, msg='spec=ALL')
>>> Password().find(12, spec=USE_LETTERS+USE_DIGITS, msg='spec=LETTERS + DIGITS')
>>> Password().find(12, spec=USE_LETTERS+USE_PUNCTATIONS, msg='spec=LETTERS + PUNCTATIONS')
>>> Password().find(12, spec=USE_DIGITS+USE_PUNCTATIONS, msg='spec=DIGITS + PUNCTATIONS')
>>>
>>> # graph to show passwords safety evolution with a certain number of tries.
>>> Password().drawGraph()

TODO:

• add pytest file
• let user choose if he wants include : digits / symbols ..etc.
• add password strength infos text.
• add improvement password suggestion in case of weak password.
• add graph representation
