Project description

https://badge.fury.io/py/django-pwned-passwords.svg https://travis-ci.org/jamiecounsell/django-pwned-passwords.svg?branch=master https://codecov.io/gh/jamiecounsell/django-pwned-passwords/branch/master/graph/badge.svg

django-pwned-passwords is a Django password validator that checks Troy Hunt’s PWNED Passwords API to see if a password has been involved in a major security breach before.

Note: This app currently sends a portion of a user’s hashed password to a third party. Before using this application, you should understand how that impacts you.

Documentation

The full documentation is at https://django-pwned-passwords.readthedocs.io.

Requirements

  • Django [1.9, 2.1]

  • Python 2.7, [3.5, 3.6, 3.7]

Quickstart

Install django-pwned-passwords:

pip install django-pwned-passwords

Add it to your INSTALLED_APPS:

INSTALLED_APPS = (
    ...
    'django_pwned_passwords',
    ...
)

Add django-pwned-passwords’s PWNEDPasswordValidator:

AUTH_PASSWORD_VALIDATORS = [
    ...
    {
        'NAME': 'django_pwned_passwords.password_validation.PWNEDPasswordValidator'
    }
]

Features

This password validator returns a ValidationError if the PWNED Passwords API detects the password in its data set. Note that the API is heavily rate-limited, so there is a timeout (PWNED_VALIDATOR_TIMEOUT).

If PWNED_VALIDATOR_FAIL_SAFE is True, anything besides an API-identified bad password will pass, including a timeout. If PWNED_VALIDATOR_FAIL_SAFE is False, anything besides a good password will fail and raise a ValidationError.

Settings

Description

Default

PWNED_VALIDATOR_TIMEOUT

2

PWNED_VALIDATOR_FAIL_SAFE

If the API fails to get a valid response, should we fail safe and allow the password through?

True

PWNED_VALIDATOR_URL

The URL for the API in a string format.

https://haveibeenpwned.com/api/v2/pwnedpassword/{short_hash}

PWNED_VALIDATOR_ERROR

The error message for an invalid password.

"Your password was determined to have been involved in a major security breach."

PWNED_VALIDATOR_ERROR_FAIL

The error message when the API fails. Note: this will only display if PWNED_VALIDATOR_FAIL_SAFE is False.

"We could not validate the safety of this password. This does not mean the password is invalid. Please try again later."

PWNED_VALIDATOR_HELP_TEXT

The help text for this password validator.

"Your password must not have been detected in a major security breach."

PWNED_VALIDATOR_MINIMUM_BREACHES

The minimum number of breaches needed to raise an error

Rate Limiting

Historically, requests to the API were rate limited. However, with the new k-anonymity model-based API, there are no such rate limits.
