# openvpn-parser [](./LICENSE-MIT) [](./LICENSE-APACHE) [](https://travis-ci.org/rusticata/openvpn-parser) [](https://crates.io/crates/openvpn-parser) ## 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: - - - OpenVPN source code - OpenVPN wireshark parser ## License Licensed under either of * Apache License, Version 2.0 ([LICENSE-APACHE](LICENSE-APACHE) or http://www.apache.org/licenses/LICENSE-2.0) * MIT license ([LICENSE-MIT](LICENSE-MIT) or http://opensource.org/licenses/MIT) at your option. ## Contribution Unless you explicitly state otherwise, any contribution intentionally submitted for inclusion in the work by you, as defined in the Apache-2.0 license, shall be dual licensed as above, without any additional terms or conditions.
