# Kerberos Parser

A Kerberos v5 ([RFC4120]) parser, implemented with the [nom](https://github.com/Geal/nom)

parser combinator framework.

The code is available on [Github](https://github.com/rusticata/kerberos-parser).

Specific parsing functions are provided for Kerberos message types. For ex. to parse a

KRB_AS_REQ message, use [`parse_as_req`](krb5_parser/fn.parse_as_req.html).

# Examples

Parsing a KRB_AS_REQ message:

```rust

use kerberos_parser::krb5::MessageType;

use kerberos_parser::krb5_parser::parse_as_req;

static AS_REQ: &'static [u8] = include_bytes!("../assets/as-req.bin");

let res = parse_as_req(AS_REQ);

match res {

    Ok((rem, kdc_req)) => {

        assert!(rem.is_empty());

        //

        assert_eq!(kdc_req.msg_type, MessageType::KRB_AS_REQ);

    },

    _ => panic!("KRB_AS_REQ parsing failed: {:?}", res),

}

```

[RFC4120]: https://tools.ietf.org/html/rfc4120

## Rusticata

This parser is part of the [rusticata](https://github.com/rusticata) project.

The goal of this project is to provide **safe** parsers, that can be used in other projects.

Testing of the parser is done manually, and also using unit tests and

[cargo-fuzz](https://github.com/rust-fuzz/cargo-fuzz). Please fill a bugreport if you find any issue.

Feel free to contribute: tests, feedback, doc, suggestions (or code) of new parsers etc. are welcome.
