Load Base64-encoded X.509 Certificate (.cer)

See more Certificates Examples

Loads a digital certificate from a base64 encoded DER X.509 Certificate (.cer, .crt) and fetches information about the cert. Dart

import 'package:chilkat/chilkat.dart';

void main() {
  final cert = CkCert();

  // LoadFromFile will load virtually any certificate format file.
  // It will auto-recognize the format and load appropiately.
  // A base64-encoded DER X.509 certificate file
  // contains the binary DER in base64 encoded form.
  // Therefore, it is a text file that will begin like this:
  // -----BEGIN CERTIFICATE-----
  // MIIFbjCCBFagAwIBAgIGdDPNv/L0MA0GCSqGSIb3DQEBBQUAMIHKMQswCQYDVQQG
  // EwJVUzEQMA4GA1UECBMHQXJpem9uYTETMBEGA1UEBxMKU2NvdHRzZGFsZTEaMBgG
  // ...

  try {
    cert.loadFromFile('/Users/chilkat/testData/cer/chilkat_base64.cer');
  } on ChilkatException catch (e) {
    print(e.lastErrorText);
    return;
  }

  // DN = "Distinguished Name"
  print('SubjectDN:${cert.subjectDN}');

  print('Common Name:${cert.subjectCN}');
  print('Issuer Common Name:${cert.issuerCN}');

  print('Serial Number:${cert.serialNumber}');
