## Overview

openvpn-parser is a parser for the ([OpenVPN](https://openvpn.net/)) protocol.

It can be used to decode the packet structures, access fields and verify some properties.
The content of the `Control` packets uses the TLS protocol, so
[tls-parser](https://github.com/rusticata/tls-parser) can be used to decode the messages.

*The parser does not decrypt messages.*

This crate mostly serves as a demo/example crate for network protocol parsers written using nom, and nom-derive.

## Notes

Writen in great pain, due to lack of specifications, and a number of fields
defined in a very useless way, like "usually 16 or 20 bytes".

Closest thing to specifications:

- <http://ipseclab.eit.lth.se/tiki-index.php?page=6.+OpenVPN>
- OpenVPN source code
