Subject Alternative Name for ICP Brasil Certs

See more Certificates Examples

Demonstrates how to access the multiple names contained in the Subject Alternative Name of a certificate. This example is for an ICP Brasil certificate. Rust

let cert = chilkat::Cert::new();

if cert.load_from_file("qa_data/certs/testIcpBrasil.cer").is_err() {
    println!("{}", cert.last_error_text());
    return;
}

// If the cert's Subject Alternative Name contains multiple values, each specified by an OID,
// then the Rfc822Name property returns XML.
let subject_alt_name_xml = cert.rfc822_name();

println!("{}", subject_alt_name_xml);

// Here's a sample of the subjectAltNameXml:

// <SubjectAltName>
//     <name type="oid" oid="2.16.76.1.3.4">290999653223955019700000000000000000000150424SRJUXPTS</name>
//     <name type="oid" oid="2.16.76.1.3.2">JOAO SILVA</name>
//     <name type="oid" oid="2.16.76.1.3.3">02408939000115</name>
//     <name type="oid" oid="2.16.76.1.3.7">000000000000</name>
// </SubjectAltName>

// The XML can be parsed like this:

let xml = chilkat::Xml::new();
let _ = xml.load_xml(&subject_alt_name_xml);

let mut oid = String::new();
let mut name = String::new();

let mut i = 0;
let count_i = xml.num_children_having_tag("name");
while i < count_i {
    xml.set_i(i);
    oid = xml.chilkat_path("name[i]|(oid)").unwrap_or_default();
    name = xml.get_child_content("name[i]").unwrap_or_default();
    println!("{}: {}", oid, name);
    i = i + 1;
}
