django-passwords is a reusable app that provides a form field and validators that check the strength of a password.
You can install django-passwords with pip by typing::
pip install django-passwords
Or with easy_install by typing::
easy_install django-passwords
Or manually by downloading a tarball and typing::
python setup.py install
django-passwords is compatible with Django 1.3 through 1.9 RC1. Pythons 2.7 and 3.4 are both supported.
django-passwords adds 6 optional settings
Optional: Specifies minimum length for passwords::
PASSWORD_MIN_LENGTH = 6 # Defaults to 6
Specifies maximum length for passwords::
PASSWORD_MAX_LENGTH = 120 # Defaults to None
Specifies the location of a dictionary (file with one word per line)::
PASSWORD_DICTIONARY = "/usr/share/dict/words" # Defaults to None
Specifies how close a fuzzy match has to be to be considered a match::
PASSWORD_MATCH_THRESHOLD = 0.9 # Defaults to 0.9, should be 0.0 - 1.0 where 1.0 means exactly the same.
Specifies a list of common sequences to attempt to match a password against::
PASSWORD_COMMON_SEQUENCES = [] # Should be a list of strings, see passwords/validators.py for default
Specifies number of characters within various sets that a password must contain::
PASSWORD_COMPLEXITY = { # You can omit any or all of these for no limit for that particular set
"UPPER": 1, # Uppercase
"LOWER": 1, # Lowercase
"LETTERS": 1, # Either uppercase or lowercase letters
"DIGITS": 1, # Digits
"SPECIAL": 1, # Not alphanumeric, space or punctuation character
"WORDS": 1 # Words (alphanumeric sequences separated by a whitespace or punctuation character)
}
To use the formfield simply import it and use it:
.. code-block:: python
from django import forms
from passwords.fields import PasswordField
class ExampleForm(forms.Form):
password = PasswordField(label="Password")
You can make use of the validators on your own fields:
.. code-block:: python
from django import forms
from passwords.validators import dictionary_words
field = forms.CharField(validators=[dictionary_words])
You can also create custom validator instances to specify your own field-specific configurations, rather than using the global configurations:
.. code-block:: python
from django import forms
from passwords.validators import (
DictionaryValidator, LengthValidator, ComplexityValidator)
field = forms.CharField(validators=[
DictionaryValidator(words=['banned_word'], threshold=0.9),
LengthValidator(min_length=8),
ComplexityValidator(complexities=dict(
UPPER=1,
LOWER=1,
DIGITS=1
)),
])
