Expand description

X.509 Certificate parser

This object is a parser builder, and allows specifying parsing options. Currently, the only option is to control deep parsing of X.509v3 extensions: a parser can decide to skip deep-parsing to be faster (the structure of extensions is still parsed, and the contents can be parsed later using the from_der method from individual extension objects).

This object uses the nom::Parser trait, which must be imported.

§Example

To parse a certificate without parsing extensions:

use x509_parser::certificate::X509CertificateParser;
use x509_parser::nom::Parser;

// create a parser that will not parse extensions
let mut parser = X509CertificateParser::new()
    .with_deep_parse_extensions(false);
let res = parser.parse(DER);
match res {
    Ok((_rem, x509)) => {
        let subject = x509.subject();
        let issuer = x509.issuer();
        println!("X.509 Subject: {}", subject);
        println!("X.509 Issuer: {}", issuer);
    },
    _ => panic!("x509 parsing failed: {:?}", res),
}
