# tls-dashboard
A dashboard written in JavaScript & HTML to check the remaining time before a TLS certificate expires. A combination of a Node module and an HTML/CSS/JS webpage to display the info.

## Node Setup
### `node_app/config.js`
Copy `node_app/example_config.js` to `node_app/config.js`. You won't need to change the defaults unless you want a special snowflake. Contains the configuration variables for the node script, as described below.  

* `connection_timeout` - The time in milliseconds that node should leave a connection open without response after the socket has been assigned. Once the timeout expires, node emits a `timeout` event and aborts the connection request. Default is 5000ms.  
* `output_file`  
  * `path` - The path to the directory that you want the output file written to. Can be relative or absolute, requires a trailing `/`, and defaults to the `../web_service/js/tls-dashboard/` directory. If you move the contents of the `./web_service` directory, make sure you update this path.  
  * `name` - The name of the output file. This typically doesn't need to be changed, but if you do change it, you'll also need to change the filename in `index.html` at line 14.  


### `node_app/monitored_hosts.js`
Copy the `node_app/example_monitored_hosts.js` to `node_app/monitored_hosts.js`. Contains an array of all of the hostnames that you want to monitor. Modify this array for all of the hosts that you want to monitor.  

### `node_app/get_cert_info.js`
This module performs the actual HTTPS connection and evaluation of the peer certificates, and outputs the results into a flat file. There are no configuration changes needed in this file. To get things going, you can either:  

1. Run the script manually whenever you need to update your dashboard by calling `node get_cert_info.js`; or   
2. Set up the script to run on a cronjob

It's entirely up to you how you want to handle it.

## Web Service Setup
### Development
If you're using this on a local machine, and you haven't made any changes to the default config, then once you've ran `node get_cert_info.js` as described above, all you have to do is open the `web_service/index.html` file in your browser of choice. All of the dependencies are there and the links are relative, so you should be good to go.

### Production
To get the web service started on a remote server, you'll need to either move the contents of the `web_service` directory to somewhere in your web site's path, or create a symlink (recommended if you're using Git to deploy) from the web site path back to the directory. If you move the contents, please update the `output_file.path` config value. Again, since all of the Dashbaord's dependencies are in the `web_service` directory, and the links are relative links, there's nothing else you need to change.

## Example
Take a look at a live example page [here on GitLab][1]. Screenshots below.

## TODO
1. Database integration?  
2. Slack integration?  
3. Monitor CRLs  
4. Non-standard ports/paths?

## Dependencies
The node module has no dependencies external to the node core. The following dependencies are provided for the web service to render properly.

* jQuery v2.2.2  
* Handlebars v4.0.5  
* Bootstrap v4.0.0-alpha (CSS only)
