django-data-masker 1.1.1

A simple Django app to mask sensitive data in forms.

Data Masker is a simple Django app to do data masking. It masks sensitive data by name of form fields and is highly configurable. Currently CharField and EmailField are supported.

Quick start

1. Add data_masker to your INSTALLED_APPS setting like this:

   INSTALLED_APPS = [
       ...
       'data_masker',
   ]

2. In template, pass the form which contains sensitive data to mask_form tag before any rendering tags.

Example template

{# Load the tag library #}
{% load data_masker %}

{# Display a form #}
<form action="/url/to/submit/" method="post" class="form">
  {% csrf_token %}
  {# Mask the form #}
  {% mask_form form as masked_form %}
  {{ masked_form }}

  {# It also works well with django-bootstrap #}
  {% comment %}
  {% bootstrap_form masked_form %}
  {% endcomment %}

  <button type="submit">Submit</button>
</form>
