Error Event (WebDAVServer Component)

Information about errors during data delivery.

Syntax

• C#
• VB.NET

  public long ConnectionID { get; }
  public int ErrorCode { get; }
  public bool Fatal { get; }
  public bool Remote { get; }

  Public ReadOnly Property ConnectionID As Long
  Public ReadOnly Property ErrorCode As Integer
  Public ReadOnly Property Fatal As Boolean
  Public ReadOnly Property Remote As Boolean
  Public ReadOnly Property Description As String

ExternalSign Event (WebDAVServer Component)

Handles remote or external signing initiated by the server protocol.

Syntax

• C#
• VB.NET

public event OnExternalSignHandler OnExternalSign;

public delegate void OnExternalSignHandler(object sender, WebDAVServerExternalSignEventArgs e);

public class WebDAVServerExternalSignEventArgs : EventArgs {
  public long ConnectionID { get; }
  public string OperationId { get; }
  public string HashAlgorithm { get; }
  public string Pars { get; }
  public string Data { get; }
  public string SignedData { get; set; }
}

Public Event OnExternalSign As OnExternalSignHandler

Public Delegate Sub OnExternalSignHandler(sender As Object, e As WebDAVServerExternalSignEventArgs)

Public Class WebDAVServerExternalSignEventArgs Inherits EventArgs
  Public ReadOnly Property ConnectionID As Long
  Public ReadOnly Property OperationId As String
  Public ReadOnly Property HashAlgorithm As String
  Public ReadOnly Property Pars As String
  Public ReadOnly Property Data As String
  Public Property SignedData As String
End Class

Remarks

Assign a handler to this event if you need to delegate a low-level signing operation to an external, remote, or custom signing engine. Depending on the settings, the handler will receive a hashed or unhashed value to be signed.

The event handler must pass the value of Data to the signer, obtain the signature, and pass it back to the component via the SignedData parameter.

OperationId provides a comment about the operation and its origin. It depends on the exact component being used, and may be empty. HashAlgorithm specifies the hash algorithm being used for the operation, and Pars contains algorithm-dependent parameters.

The component uses base16 (hex) encoding for the Data, SignedData, and Pars parameters. If your signing engine uses a different input and output encoding, you may need to decode and/or encode the data before and/or after the signing.

A sample MD5 hash encoded in base16: a0dee2a0382afbb09120ffa7ccd8a152 - lower case base16 A0DEE2A0382AFBB09120FFA7CCD8A152 - upper case base16

A sample event handler that uses the .NET RSACryptoServiceProvider class may look like the following: signer.OnExternalSign += (s, e) => { var cert = new X509Certificate2("cert.pfx", "", X509KeyStorageFlags.Exportable); var key = (RSACryptoServiceProvider)cert.PrivateKey; var dataToSign = e.Data.FromBase16String(); var signedData = key.SignHash(dataToSign, "2.16.840.1.101.3.4.2.1"); e.SignedData = signedData.ToBase16String(); };
