Subject Alternative Name

See more Certificates Examples

Demonstrates the usage of the SubjectAlternativeName property to get the certificate SAN (subject alternative name) as XML. React Native

import { Cert, Xml } from '@chilkat/react-native'

function chilkatExample() {
  // Note: Not all certificates contain a Subject Alternative Name.
  // If it does not, the SubjectAlternativeName property will contain the empty string.

  const cert = new Cert();

  try {
    cert.loadFromFile('qa_data/certs/testIcpBrasil.cer');
  } catch {
    console.log(cert.lastErrorText);
    return;
  }

  const subjectAltNameXml = cert.subjectAlternativeName;

  console.log(subjectAltNameXml);

  // Here's a sample of the subjectAltNameXml:

  // <?xml version="1.0" encoding="utf-8"?>
  // <SubjectAltName>
  //     <name type="oid" oid="2.16.76.1.3.4">...</name>
  //     <name type="oid" oid="2.16.76.1.3.2">...</name>
  //     <name type="oid" oid="2.16.76.1.3.3">...</name>
  //     <name type="oid" oid="2.16.76.1.3.7">...</name>
  //     <rfc822Name>...</rfc822Name>
  // </SubjectAltName>

  // The XML can be parsed like this:

  const xml = new Xml();

  xml.loadXml(subjectAltNameXml);

  let oid = '';
  let name = '';

  let i = 0;
  const countI = xml.numChildrenHavingTag('name');
  while (i < countI) {
    xml.i = i;
    oid = xml.chilkatPath('name[i]|(oid)');
    name = xml.getChildContent('name[i]');
    i++;
  }

  const rfc822Name = xml.getChildContent('rfc822Name');
