Use HTTPS Client Certificate from .cer and .key Files

See more HTTP Examples

Demonstrates how to load a cert + private key from .cer and .key (base64) files and use it for mutual TLS authentication (client-side certificate). React Native

import { BinData, Cert, Http, PrivateKey } from '@chilkat/react-native'

function chilkatExample() {
  // This example requires the Chilkat API to have been previously unlocked.
  // See Global Unlock Sample for sample code.

  const http = new Http();

  const cert = new Cert();
  const privKey = new PrivateKey();

  // Load any type of certificate (.cer, .p7b, .pem, etc.) by calling LoadFromFile.
  try {
    cert.loadFromFile('qa_data/certs/sample_cert_a.cer');
  } catch {
    console.log(cert.lastErrorText);
    return;
  }

  // Load the private key.
  const bd = new BinData();
  bd.loadFile('qa_data/certs/sample_key_a.key');
  try {
    privKey.loadAnyFormat(bd, 'privateKeyPasswordIfNecessary');
  } catch {
    console.log(privKey.lastErrorText);
    return;
  }

  // Associate the private key with the cert.
  try {
    cert.setPrivateKey(privKey);
  } catch {
    console.log(cert.lastErrorText);
    return;
  }

  // Set the certificate to be used for mutual TLS authentication
  // (i.e. sets the client-side certificate for two-way TLS authentication)
  try {
    http.setSslClientCert(cert);
  } catch {
    console.log(http.lastErrorText);
    return;
  }

  // At this point, the HTTP object instance is setup with the client-side cert, and any SSL/TLS
  // connection will automatically use it if the server demands a client-side cert.
