**Certstream-server** is a server written in python3 to aggregate, parse, and stream certificate data from multiple [certificate transparency logs](https://www.certificate-transparency.org/what-is-ct). It leverages concurrency to be relatively efficient and handle many clients at the same time.

## Getting Started

Getting up and running is pretty easy (especially if you use Heroku, as we include a Procfile!), simply clone this repo and run:

```
# Install Dependencies
pip install -r requirements.txt

# Run CertStream
python run_server.py
```

Or if python3 isn't your default interpreter:

```
# Install Dependencies
pip3 install -r requirements.txt

# Run CertStream
python3 run_server.py
```

**Note** Running the server requires at least python 3.6, as we use the new `async`/`await` syntax internally.

This will open up an http/websocket server on port 8080 (override this by setting a `PORT` environment variable). Connecting to it with a websocket client will subscribe you to a live aggregated stream of certificates and heartbeat messages.

Connecting over a normal HTTP connection will show the certstream frontpage (currently being re-written).

## HTTP Routes

`/latest.json` - Get the most recent 25 certificates CertStream has seen

`/example.json` - Get the most recent certificate CertStream has seen

`/stats` - Get statistics on the connected clients (override by setting the `STATS_URL` environment variable - we do this for [certstream.calidog.io](https://certstream.calidog.io)).

## Websocket Channels

Channels are a feature that is currently in development (and aren't quite in yet), but the idea is that it will allow you to get a subset of the data instead of an entire data packet for each update message you receive. Sometimes you only care about the leaf certificate (so we'll omit the chain), and sometimes you don't want a copy of the certificates themselves (in which case we'll omit those).

## Data Structures

There are currently only 2 data structures that certstream produces:

**Heartbeats**

```
{
    "message_type": "heartbeat",
    "timestamp": 1508532970.93171
}
```

**Certificate Updates**
