Dart Requires Chilkat v11.0.0+

Iterate Keys and Certs in PEM

See more PEM Examples

Demonstrates how to access each of the private keys and certs contained within 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.

  final pem = CkPem();

  // Load the PEM from a file.
  // If the PEM is encrypted, provide a password.  Otherwise pass an empty string for the password.
  final password = 'myPassword';
  try {
    pem.loadPemFile('../myPemFiles/myPem.pem', password);
  } on ChilkatException catch (e) {
    print(e.lastErrorText);
    return;
  }

  // Note: If the app already has the PEM pre-loaded in a string variable, then load it 
  // by calling LoadPem instead.  
  final pemContent = '... the PEM contents ...';
  pem.loadPem(pemContent, password);
  // Check for success as before..

  // Iterate over the private keys.
  final numPrivateKeys = pem.numPrivateKeys;
  var i = 0;

  final privKey = CkPrivateKey();
  while (i < numPrivateKeys) {
    pem.privateKeyAt(i, privKey);
    print('Private Key $i is ${privKey.bitLength} in length');
    i++;
  }

  // Iterate over the certificates.
  final cert = CkCert();
  final numCerts = pem.numCerts;
  i = 0;
  while (i < numCerts) {
    pem.certAt(i, cert);
    print('Certificate $i : ${cert.subjectDN}');
    i++;
  }
}
