X.509 Parser

A X.509 (RFC5280) parser, implemented with the nom parser combinator framework.

The code is available on Github and is part of the Rusticata project.

The main parsing method is parse_x509_der, which takes a DER-encoded certificate as input, and builds a X509Certificate object.

For PEM-encoded certificates, use the pem module.

Examples

Parsing a certificate in DER format:

# extern crate nom;
# #[macro_use] extern crate x509_parser;
use x509_parser::parse_x509_der;

static IGCA_DER: &'static [u8] = include_bytes!("../assets/IGC_A.der");

# fn main() {
let res = parse_x509_der(IGCA_DER);
match res {
Ok((rem, cert)) => {
assert!(rem.is_empty());
//
assert_eq!(cert.tbs_certificate.version, 2);
},
_ => panic!("x509 parsing failed: {:?}", res),
}
# }
