(Android™) Get Certificate Valid To/From DatesDemonstrates how to get the certificate "valid from" and "valid to" dates.
// Important: Don't forget to include the call to System.loadLibrary // as shown at the bottom of this code sample. package com.test; import android.app.Activity; import com.chilkatsoft.*; import android.widget.TextView; import android.os.Bundle; public class SimpleActivity extends Activity { private static final String TAG = "Chilkat"; // Called when the activity is first created. @Override public void onCreate(Bundle savedInstanceState) { super.onCreate(savedInstanceState); CkCert cert = new CkCert(); boolean success = cert.LoadFromFile("qa_data/certs/testCert.cer"); if (success != true) { Log.i(TAG, cert.lastErrorText()); return; } // Get the certificate valid-from date/time CkDateTime ckdt = cert.GetValidFromDt(); // Get the local timestamp string. Log.i(TAG, "Valid from: " + ckdt.getAsTimestamp(true)); // Valid from: 2017-03-17T19:00:00-05:00 // Now get the date/time as another object where we can get the individual numeric date parts. CkDtObj dt = ckdt.GetDtObj(true); Log.i(TAG, String.valueOf(dt.get_Day()) + "/" + String.valueOf(dt.get_Month()) + "/" + String.valueOf(dt.get_Year()) + " " + String.valueOf(dt.get_Hour()) + ":" + String.valueOf(dt.get_Minute())); // Get the certificate valid-to date/time ckdt = cert.GetValidToDt(); Log.i(TAG, "Valid to: " + ckdt.getAsTimestamp(true)); // Valid to: 2020-03-18T18:59:59-05:00 dt = ckdt.GetDtObj(true); Log.i(TAG, String.valueOf(dt.get_Day()) + "/" + String.valueOf(dt.get_Month()) + "/" + String.valueOf(dt.get_Year()) + " " + String.valueOf(dt.get_Hour()) + ":" + String.valueOf(dt.get_Minute())); } static { System.loadLibrary("chilkat"); // Note: If the incorrect library name is passed to System.loadLibrary, // then you will see the following error message at application startup: //"The application <your-application-name> has stopped unexpectedly. Please try again." } } |
