SSLServerAuthentication Event

For asynchronous HTTPS MDNs, fired after the server presents its certificate.

Syntax

• C#
• VB.NET

public event OnSSLServerAuthenticationHandler OnSSLServerAuthentication;

public delegate void OnSSLServerAuthenticationHandler(object sender, As2receiverSSLServerAuthenticationEventArgs e);

public class As2receiverSSLServerAuthenticationEventArgs : EventArgs {
  public string CertEncoded { get; }
  public byte[] CertEncodedB { get; }
  public string CertSubject { get; }
  public string CertIssuer { get; }
  public string Status { get; }
  public bool Accept { get; set; }
}

Public Event OnSSLServerAuthentication As OnSSLServerAuthenticationHandler

Public Delegate Sub OnSSLServerAuthenticationHandler(sender As Object, e As As2receiverSSLServerAuthenticationEventArgs)

Public Class As2receiverSSLServerAuthenticationEventArgs Inherits EventArgs
  Public ReadOnly Property CertEncoded As String
  Public ReadOnly Property CertEncodedB As Byte()
  Public ReadOnly Property CertSubject As String
  Public ReadOnly Property CertIssuer As String
  Public ReadOnly Property Status As String
  Public Property Accept As Boolean
End Class

Remarks

This event is fired when returning asynchronous MDNs over HTTPS to the client, and allows the client can decide whether to continue with the connection process or not. In general, the component will allow self-signed certs only if explicitly specified.

To accept a self-signed certificate, either trap the SSLServerAuthentication event and set Accept to true based on the values of CertSubject, CertEncoded, etc., or set the SSLAcceptServerCert property to the value of the expected certificate (if the server certificate is known in advance the latter method is simpler).
