[−][src]Crate openvpn_parser
openvpn-parser
Overview
openvpn-parser is a parser for the (OpenVPN) 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 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
