Load Default Certificate from Smart Card or Token

See more Certificates Examples

Chilkat contains internal logic to examine a connected smart card or USB token, and will make decisions based on make/model to successfully interact with the hardware. When faced with a new smartcard or token, the best starting point is to call LoadFromSmartcard with an empty string argument to see what Chilkat discovers. React Native

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

function chilkatExample() {
  const cert = new Cert();

  // If you know the smart card PIN, it's good to set it prior to loading from the smartcard/USB token.
  cert.smartCardPin = '12345678';

  // To let Chilkat discover what smartcard or token is connected, pass an empty string to LoadFromSmartcard.
  // When testing in this way, it's best to have only a single smartcard or token connected to the system.
  try {
    cert.loadFromSmartcard('');
  } catch {
    console.log(cert.lastErrorText);
    console.log('Certificate not loaded.');
    return;
  }

  // The LastErrorText property on all Chilkat objects will contain 
  // information even when the method call is successful.
  // You can examine the LastErrorText to see what Chilkat found and
  // what decisions were made.
  // 
  // For example, if a certificate was successfully loaded via LoadFromSmartcard,
  // but then signing failed, such as w/ Pdf, XmlDSig, CAdES, etc.,
  // then we would want to examine the LastErrorText from the call to
  // LoadFromSmartcard to get detailed information about the card.
  console.log(cert.lastErrorText);

  console.log(`Found: ${cert.subjectDN} serial=${cert.serialNumber}`);
