'Get the encrypted value in django-fernet-fields

I use the django-fernet-fields library:

class RoutePoint(models.Model):
    username = models.CharField(max_length=30)
    password = EncryptedCharField(max_length=30, null=True)

When I access an encrypted field, the value of the field is automatically decrypted.

p = RoutePoint.objects.all()[0]
print(p.password)
> mypass

Is there any way I can get the encrypted value that is actually stored in the database?

Solution 1:[1]

The method that performs the decryption within the model.Field is def from_db_value(self, value, expression, connection, *args). In theory, you could override this method for RoutePoint.password and have it return a tuple, with the first element being the raw field value and the second being the decrypted plaintext.

Here is a pointer to the relevant source code https://github.com/orcasgit/django-fernet-fields/blob/master/fernet_fields/fields.py#L74.

Note: django-fernet-fields hasn't been updated in over 3 years, and as a previous user myself, I forked the codebase to one that is backed by Google Tink instead https://github.com/script3r/django-tink-fields

Use next() instead of nextLine(). nextLine() reads inputs including the space between the words. A space will be read as empty String. If you are using next(), it will not read blank lines at all. It reads the input till the space.
