Crate x509_parser

X.509 Parser

A X.509 v3 (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:

use x509_parser::parse_x509_der;

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

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),
}
