Add Private Key and Certificate to a PEM

See more PEM Examples

Demonstrates how to add certificates and private keys to a PEM. Dart

import 'package:chilkat/chilkat.dart';

void main() {
  // This example assumes the Chilkat API to have been previously unlocked.
  // See Global Unlock Sample for sample code.

  // The Chilkat PEM class was introduced in v9.5.0.49.  
  // It requires the bundle to be unlocked, as shown above.
  final pem = CkPem();

  // Add the private key found in alice.key to this PEM.
  // 
  final privKey = CkPrivateKey();

  try {
    privKey.loadAnyFormatFile('qa_data/alice.key', '');
  } on ChilkatException catch (e) {
    print(e.lastErrorText);
    return;
  }

  // Add it to the PEM:
  pem.addPrivateKey(privKey);

  // Add the certificate found in alice.crt to this PEM.
  // 
  final cert = CkCert();

  try {
    cert.loadFromFile('qa_data/alice.crt');
  } on ChilkatException catch (e) {
    print(e.lastErrorText);
    return;
  }

  // Add it to the PEM:
  final includeCertChain = false;
  pem.addCert(cert, includeCertChain);

  // Write the PEM containing the private key and certificate.
  // The private key will be output in PKCS8 encrypted form.
  // Certificates are never encrypted.

  // This is the password that will be required to open and access the private key
  // from the PEM we're about to write..
  final password = 'secret';
  final extendedAttrs = false;
  final noKeys = false;
  final noCerts = false;
  final noCaCerts = false;
  final encryptAlg = 'aes128';

  final pemStr = pem.toPemEx(extendedAttrs, noKeys, noCerts, noCaCerts, encryptAlg, password);
  print(pemStr);
