# Dealdoh
> Play with DNS over HTTPS and much more!
Dealdoh is a DNS-over-HTTPS (DoH) proxy and a library around DNS messaging written in PHP.
[](https://travis-ci.org/noglitchyo/dealdoh)
[](https://codecov.io/gh/noglitchyo/dealdoh)
## Overview
This library gives ability to proxy DoH requests and/or to send DNS queries with standard UDP/TCP and various modern and secure DNS protocols like DNSCrypt, DNS-over-HTTPS (DoH), GoogleDNS.
It attempts to achieve the following goals:
- provide high-compatibility with a large variety of DNS protocols.
- provide a well-designed abstraction layer for development around DNS in PHP.
## Features
- [x] DoH proxy middleware PSR-15/PSR-7 compliant.
- [x] Create and forward DNS messages to different type of DNS upstream resolvers.
- [x] Forward DNS query through multiple DNS upstream resolvers.
- [x] Compatible with DNS protocols: RFC-1035 (Plain DNS over TCP/UDP), RFC-8484 (DoH), Google DoH API, DNSCrypt
- [x] Abstraction layer around DNS development.
- [x] Parse [DNS stamps](https://dnscrypt.info/stamps-specifications)
## Client
[dealdoh-client](https://github.com/noglitchyo/dealdoh-client/) is a CLI utility which offers a ready-to-use implementation
of this library to send and forward DNS queries.
## Library
#### Requirements
- PHP 7.3
- Web server
- Optional: HTTPS enabled with valid certificates (self-signed certificates can work but it depends of the DOH client making the queries)
#### Installation
- Run `composer require noglitchyo/dealdoh`
- `DohResolverMiddleware::forward()` method consumes PSR-7 ServerRequest.
Some compatible implementations which can be used:
* https://github.com/Nyholm/psr7 - `composer require nyholm/psr7`
* https://github.com/guzzle/psr7 - `composer require guzzle/psr7`
* https://github.com/zendframework/zend-diactoros - `composer require zendframework/zend-diactoros`
- Configure your application to call `DohResolverMiddleware::forward()`
- Testing the installation
As recommended in RFC-8484, usually, DoH client/server will send/receive DNS requests on the path: `/dns-query`.
Your application should be configured to listen on this route.
A large variety of DoH client exists than can be used to test the installation.
* [dealdoh-client](https://github.com/noglitchyo/dealdoh-client/)
* [Facebook Experimental](https://github.com/facebookexperimental/doh-proxy)
* Using client from Web Browser
Mozilla Firefox provides a [Trusted Recursive Resolver](https://wiki.mozilla.org/Trusted_Recursive_Resolver) who can be configured to query DoH servers.
[This article from Daniel Stenberg](https://daniel.haxx.se/blog/2018/06/03/inside-firefoxs-doh-engine/)
provides a lot of details about TRR and how to configure it.
Please check also [the browser implementations list](https://github.com/curl/curl/wiki/DNS-over-HTTPS#supported-in-browsers-and-clients).
#### Example
```php
forward(/* Expect a \Psr\Http\Message\RequestInterface object */);
```
#### More examples
Checkout some really simple integration examples to get a glimpse on how it can be done:

- [DoH + Docker + DNS + Hostname Discovery](examples/docker-firefox/README.md)

## Testing
If you wish to run the test, checkout the project and run the test with:
`composer test`
