django-encrypted-id-cryptography is a Django model which allows the use of encrypted ids for when you don't want to expose the regular pk.
**Note: This is a fork from django-encrypted-id and acts *mostly* a drop in replacement, it requires an additional settings and the encrypted ids are not compaitable. It also uses a different crypto library**
Requirements
------------
The following have been tested, however it should work with more.
* Django [1.11, 2.0, 2.2]
* Python [2.7, 3.5]
* Cryptography
Quickstart
----------
Install django-encrypted-id-cryptography::
pip install django-encrypted-id-cryptography
Create an encryption key:
.. code-block:: python
> from cryptography.fernet import Fernet
> Fernet.generate_key()
'3CNek72sQ3syTXX6h-Z1t3OLKKY1lfAgnTW_THUz37M='
.. code-block:: python
ID_ENCRYPT_KEY = ['3CNek72sQ3syTXX6h-Z1t3OLKKY1lfAgnTW_THUz37M=']
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 (:code:`PWNED_VALIDATOR_TIMEOUT`).
If :code:`PWNED_VALIDATOR_FAIL_SAFE` is True, anything besides an API-identified bad password
will pass, including a timeout. If :code:`PWNED_VALIDATOR_FAIL_SAFE` is False, anything
besides a good password will fail and raise a ValidationError.
Use
--------
Consider this example model:
.. code-block:: python
from django.db import models
from encrypted_id.models import EncryptedIDModel
class Foo(EncryptedIDModel):
text = models.TextField()
By inheriting from ``EncryptedIDModel``, you get .ekey as a property on your
model instances. This is how they will look like:
.. code-block:: python
In [1]: from tapp.models import Foo
In [2]: f = Foo.objects.create(text="asd")
In [3]: f.id
Out[3]: 1
In [4]: f.ekey
Out[4]: 'gAAAAABcyQ2WlhRT6zec6WCRMJ3mDkZL9SCy98JeMvrERki6DJgc3WeIRMbAMm86_zmV0sP3_iPvbAHGgb7RfEGrnIIYdggaig=='
You can do reverse lookup:
In [5]: from encrypted_id import decode
In [6]: decode(f.ekey)
Out[6]: 1
If you can not inherit from the helper base class, no problem, you can just use
the ``ekey()`` function from ``encrypted_id`` package:
.. code-block:: python
In [7]: from encrypted_id import ekey
In [8]: from django.contrib.auth.models import User
In [9]: ekey(User.objects.get(pk=1))
Out[9]: 'gAAAAABcyQ2WlhRT6zec6WCRMJ3mDkZL9SCy98JeMvrERki6DJgc3WeIRMbAMm86_zmV0sP3_iPvbAHGgb7RfEGrnIIYdggaig=='
To do the reverse lookup, you have two helpers available. First is provided by
``EncryptedIDManager``, which is used by default if you inherit from
``EncryptedIDModel``, and have not overwritten the ``.objects``:
.. code-block:: python
In [10]: Foo.objects.get_by_ekey(f.ekey)
Out[10]: <Foo: Foo object>
But sometimes you will prefer the form:
.. code-block:: python
In [11]: Foo.objects.get_by_ekey_or_404(f.ekey)
Out[11]: <Foo: Foo object>
Which works the same, but instead of raising ``DoesNotExist``, it raises
``Http404``, so it can be used in views.
You your manager is not inheriting from ``EncryptedIDManager``, you can use:
.. code-block:: python
In [12]: e = ekey(User.objects.first())
In [13]: e
Out[13]: 'gAAAAABcyQ2WlhRT6zec6WCRMJ3mDkZL9SCy98JeMvrERki6DJgc3WeIRMbAMm86_zmV0sP3_iPvbAHGgb7RfEGrnIIYdggaig=='
In [14]: get_object_or_404(User, e)
Out[14]: <User: amitu>
``encrypted_id.get_object_or_404``, as well as
``EncryptedIDManager.get_by_ekey`` and
``EncryptedIDManager.get_by_ekey_or_404`` take extra keyword argument, that can
be used to filter if you want.
If you are curious, the regex used to match the generated ids is:
.. code-block:: python
"[0-9a-zA-Z-_=]+"
