<p align="center"><em>Secweb helps in setting security headers for FastApi and Starlette</em></p>

---
<br>

Secweb is the pack of middlewares for setting security headers for fastapi and can also be used for any framework created on starlette it has 14 middlewares for setting headers of your website and also for your api`s

#### The PermissionsPolicy middleware lies in development branch [here](https://github.com/tmotagam/Secweb/tree/Secweb-Beta#readme)

The list of middleware is as follows:

1. Content Security Policy (CSP)
<br>

2. ExpectCT
<br>

3. Origin Agent Cluster
<br>

4. Referrer Policy
<br>

5. HTTP Strict Transport Security(HSTS)
<br>

6. X-Content-Type-Options
<br>

7. X-DNS-Prefetch-Control
<br>

8. X-Download-Options
<br>

9. X-Frame
<br>

10. X-Permitted-Cross-Domain-Policies
<br>

11. X-XSS-Protection
<br>

12. Cross-Origin-Embedder-Policy
<br>

13. Cross-Origin-Opener-Policy
<br>

14. Cross-Origin-Resource-Policy

## Requirements

* [Python >= 3.6](https://www.python.org/downloads/)

* [Starlette](https://pypi.org/project/starlette/)

## Installation

```powershell
pip install Secweb
```
## Usage
The package Secweb can be used in two different ways

1. To use SecWeb class it includes all the 14 classes together
<br>

2. To use the 14 middleware classes separately
<br>

### SecWeb class

```Python
from Secweb import SecWeb

SecWeb(app=app)  # The app is the ASGIapp required by the starlette to give access to the different methods to the class
```
The above example uses all the default headers value that are are preset you can change the values by creating the option dict you can also set flags for nonce generation for csp header using the `script_nonce=True` and `style_nonce=True` flags

```Python
from Secweb import SecWeb

SecWeb(app=app, Option={'referrer': {'Referrer-Policy': 'no-referrer'}}, script_nonce=False, style_nonce=False)
```
The Option uses 11 keys for calling middleware classes to set the user-defined policies. 3 middleware classes doesn`t take any values.

The values are as follows:

1. `'csp'` for calling ContentSecurityPolicy class to set the user-defined values
<br>

2. `'expectCt'` for calling ExpectCt class to set the user-defined values
<br>

3. `'referrer'` for calling ReferrerPolicy class to set the user-defined values
<br>

4. `'xdns'` for calling XDNSPrefetchControl class to set the user-defined values
<br>

5. `'xcdp'` for calling XPermittedCrossDomainPolicies class to set the user-defined values
<br>

6. `'hsts'` for calling HSTS class to set the user-defined values
<br>

7. `'xss'` for calling xXSSProtection class to set the user-defined values
<br>

8. `'xframe'` for calling XFrame class to set the user-defined values
<br>

9. `'coep'` for calling CrossOriginEmbedderPolicy class to set the user-defined values
<br>

10. `'coop'` for calling CrossOriginOpenerPolicy class to set the user-defined values
<br>

11. `'corp'` for calling CrossOriginResourcePolicy class to set the user-defined values

```python
# Example of the values
SecWeb(app=app, Option={'csp': {'default-src': ["'self'"]}, 'xframe': {'X-Frame-Options': 'SAMEORIGIN'}, 'xss': {'X-XSS-Protection': '1; mode=block'}, 'hsts': {'max-age': 4, 'preload': True}, 'xcdp': {'X-Permitted-Cross-Domain-Policies': 'all'}, 'xdns': {'X-DNS-Prefetch-Control': 'on'}, 'referrer': {'Referrer-Policy': 'no-referrer'}, 'expectCt': {'max-age': 128, 'enforce': True, 'report-uri': "https://example.com/example"}, 'coep': {'Cross-Origin-Embedder-Policy': 'require-corp'}, 'coop': {'Cross-Origin-Opener-Policy': 'same-origin-allow-popups'}, 'corp': {'Cross-Origin-Resource-Policy': 'same-site'}})
```
### Middleware Classes

#### Content Security Policy (CSP)

ContentSecurityPolicy class sets the csp header

The Nonce_Processor module generates nonce for csp header

Nonce Processor

```python
    # Some Code
    nonce = Nonce_Processor(DEFAULT_ENTROPY=20)  # inject the nonce variable into the jinja or html
    # Some Code
```
DEFAULT_ENTROPY is used to set the nonce length.
The nonce processor needs to be called on the route the following example is of FastApi calling the nonce processor on the route

```python
from fastapi import FastAPI
from Secweb.ContentSecurityPolicy import Nonce_Processor

app = FastAPI()


@app.get("/")
async def root():
    # some code
    nonce = Nonce_Processor(DEFAULT_ENTROPY=20)  # inject the nonce variable into the jinja or html
    # some more code
```
ContentSecurityPolicy

This is for the FastApi

```python
from fastapi import FastAPI
from Secweb.ContentSecurityPolicy import Nonce_Processor

app = FastAPI()

app.add_middleware(ContentSecurityPolicy, Option={'default-src': ["'self'"], 'base-uri': ["'self'"], 'block-all-mixed-content': []}, script_nonce=False, style_nonce=False)
```

This is for the Starlette

```python
from starlette.applications import Starlette
from Secweb.ContentSecurityPolicy import Nonce_Processor

app = Starlette()

app.add_middleware(ContentSecurityPolicy, Option={'default-src': ["'self'"], 'base-uri': ["'self'"], 'block-all-mixed-content': []}, script_nonce=False, style_nonce=False)
```
script_nonce=False This is the nonce flag for inline Js

style_nonce=False This is the nonce flag for inline css
