# Krptn

**This project is archived, and not developed further. It was a developed for my personal education/entertainment.**

```shell
pip install krptn
```

## What problem do we solve?

**We all love Django and other web frameworks!** However, their primary focus is creating websites - not implementing secure storage for user data. Django makes it easy to store data. While it hashes the password, it does not encrypt user data for you. In case of a data breach, malicious actors could access any data from the DB. Encryption is left to the developer...

**Wouldn't it be nice if encryption would also be handled?** Perhaps it could be handled in a **[way that keys are derived from credentials](https://krptn.mbs9.org/news/security-model/)**, such that, without the user entering credentials, not even the database administrator can read it?! This is exactly what we do!

**We also handle user authentication, including MFA, and passwordless authentication.**

**Krptn also runs in the same server instance** as your web app. So you don't have to host anything new. Just install the extension for Python.

**To prove that such is possible, we have a [Flask](https://github.com/krptn/flaskExample) and [Django](https://github.com/krptn/djangoExample) example on GitHub.**

## What do we do exactly?

We are building a user authentication and access management system (IAM) with **[data encryption at rest derived from credentials](https://krptn.mbs9.org/news/security-model/)**. It is available as a python extension module. However we have certain [limitations](https://krptn.mbs9.org/news/limitations/).

How we achieve this?

- All data is encrypted (any data can be requested by the developer to be secured)
- Only the appropriate users' credentials can unlock the cryptosystem (this protects you from server-side attacks)

This gives you *[security from encryption](https://krptn.mbs9.org/news/security-model/)* without ever needing to even notice it! It protects you from server side attacks.

Here is an example usage:

```python
from krypton.auth.users import userModel

model = userModel.standardUser(None)
model.saveNewUser("Test_UserName", "Test_Password")
model.data.email = "test@example.com" # The email will be encrypted, and securely stored
```

## Try it out

Quickly install the package with pip for Python>3.9:

```shell
pip install krptn
```

Have a look at our [User Authentication documentation](https://docs.krptn.mbs9.org/README-USER-AUTH.html), and create some users.

Ready to integrate it into your WebApp? Have a look at some of our integration's available with [Django and Flask](https://docs.krptn.mbs9.org/README.html#integration-with-web-frameworks)!
