(C#) Get Certificate Valid To/From DatesDemonstrates how to get the certificate "valid from" and "valid to" dates.
Chilkat.Cert cert = new Chilkat.Cert(); bool success = cert.LoadFromFile("qa_data/certs/testCert.cer"); if (success != true) { Debug.WriteLine(cert.LastErrorText); return; } // Get the certificate valid-from date/time Chilkat.CkDateTime ckdt = cert.GetValidFromDt(); // Get the local timestamp string. Debug.WriteLine("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. Chilkat.DtObj dt = ckdt.GetDtObj(true); Debug.WriteLine(Convert.ToString(dt.Day) + "/" + Convert.ToString(dt.Month) + "/" + Convert.ToString(dt.Year) + " " + Convert.ToString(dt.Hour) + ":" + Convert.ToString(dt.Minute)); // Get the certificate valid-to date/time ckdt = cert.GetValidToDt(); Debug.WriteLine("Valid to: " + ckdt.GetAsTimestamp(true)); // Valid to: 2020-03-18T18:59:59-05:00 dt = ckdt.GetDtObj(true); Debug.WriteLine(Convert.ToString(dt.Day) + "/" + Convert.ToString(dt.Month) + "/" + Convert.ToString(dt.Year) + " " + Convert.ToString(dt.Hour) + ":" + Convert.ToString(dt.Minute)); |
