title: How to decrypt file using GpgAPI for c# without prompting for the password
body: <p>I've been trying to decrypt my file using GpgAPI in C#. It works fine, but it keeps prompting me for the password. The following code is what I used which is from the author's example. </p>
  
  <pre><code>public bool DecryptReport(string dataFileLocation, string filename)
          {
              log.Info("Starting GPG decryption.");
  
              GpgInterface.ExePath = @"C:\Program Files (x86)\GNU\GnuPG\gpg2.exe";
  
              String encryptedFile = dataFileLocation + filename;
              filename = filename.ToString().Substring(0, filename.ToString().IndexOf(".gpg")).ToString();
              string file = dataFileLocation + filename;
  
              try
              {
                  log.Info("Decrypting " + file);
                  GpgDecrypt decrypt = new GpgDecrypt(encryptedFile, file);
                  decrypt.AskPassphrase = GetPassword;
                  {
                      log.Info("Password received.");
                      GpgInterfaceResult result = decrypt.Execute();
                      Callback(result);
                  }
              }
              catch(Exception e)
              {
                  log.Error("Caught an exception" + e.InnerException);
                  return false;
              }
  
              return true;
          }
  
          public static string Callback(GpgInterfaceResult result)
          {
              if(result.Status == GpgInterfaceStatus.Success)
              {
                  return "successfully decrypted.";
              }
              else
              {
                  return "Error was found during decryption. Check the log.";
              }
  
          }
  
          public static SecureString GetPassword(AskPassphraseInfo arg)
          {
              return GpgInterface.GetSecureStringFromString(“password$");
  
          }
  </code></pre>
  
  <p>What am I doing wrong in this code? Why does it not pass the password and continue decrypting instead of prompting for the password? </p>
