Implement a SensitiveTextInput widget for sensitive input fields

[Håkan W]

If you're implementing Stripe, Adyen, or other big payment solutions today, then you can use client side encryption, where form fields are used for inputting e.g. credit card number (etc), but that will be encrypted before the form is submitted to the server. These fields should not be sent raw to the server, so you usually remove the name attribute on the input fields.

It would be really great if django had a SensitiveTextInput widget for purposes like this. This idea is from here: ​http://stackoverflow.com/questions/18116917/change-form-input-attribute-name-to-data-encrypted-name

Here's a suggested class:

# a text input widget with no name attribute
class SensitiveTextInput(forms.TextInput):
    def build_attrs(self, extra_attrs=None, **kwargs):
        attrs = super(SensitiveTextInput, self).build_attrs(extra_attrs, **kwargs)
        if 'name' in attrs:
            del attrs['name']
        return attrs
