        "description": "|Build Status|\n\nzxcvbn\n======\n\nA realistic password strength estimator.\n\nThis is a Python implementation of the library created by the team at Dropbox.\nThe original library, written for JavaScript, can be found\n`here <https://github.com/dropbox/zxcvbn>`__.\n\nWhile there may be other Python ports available, this one is the most up\nto date and is recommended by the original developers of zxcvbn at this\ntime.\n\n\nFeatures\n--------\n- **Tested in Python versions 2.7, 3.3-3.6**\n- Accepts user data to be added to the dictionaries that are tested against (name, birthdate, etc)\n- Gives a score to the password, from 0 (terrible) to 4 (great)\n- Provides feedback on the password and ways to improve it\n- Returns time estimates on how long it would take to guess the password in different situations\n\nInstallation\n------------\n\nInstall the package using pip: ``pip install zxcvbn``\n\nUsage\n-----\n\nPass a password as the first parameter, and a list of user-provided\ninputs as the ``user_inputs`` parameter (optional).\n\n.. code:: python\n\n    from zxcvbn import zxcvbn\n\n    results = zxcvbn('JohnSmith123', user_inputs=['John', 'Smith'])\n\n    print(results)\n\nOutput:\n\n::\n\n    {\n        'password': 'JohnSmith123',\n        'score': 2,\n        'guesses': 2567800,\n        'guesses_log10': 6.409561194521849,\n        'calc_time': datetime.timedelta(0, 0, 5204)\n        'feedback': {\n            'warning': '',\n            'suggestions': [\n                'Add another word or two.
