See more HTTP Examples

Sends an OCSP request to determine the revocation status for an SSL server certificate. Dart

import 'package:chilkat/chilkat.dart';

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

  final http = CkHttp();

  // Check the revocation status of the SSL server certificate for chilkatsoft.com
  var status = http.ocspCheck('chilkatsoft.com', 443);

  print('chilkatsoft.com status = $status');

  // The status can have 4 values:
  // -1: Unable to check because of an error.
  //  0: Good
  //  1: Revoked
  //  2: Unknown

  if (status < 0) {
    print(http.lastErrorText);
  }

  // Now check the status for a revoked server certificate.
  status = http.ocspCheck('revoked.badssl.com', 443);

  print('revoked.badssl.com status = $status');
