Configure a Socket for Server-Side TLS

See more Socket/SSL/TLS Examples

Demonstrates Socket.InitSslServer, which configures the object for server-side TLS using a server certificate that has access to its private key, then listens for and accepts a TLS connection.

The file path is relative to the application's current working directory. An absolute path may also be used. Supply the path appropriate to your own environment.

Dim success As Boolean = False

Dim socket As ChilkatSocket
socket.Initialize("socket")

'  The file path is relative to the application's current working directory.  An absolute path
'  may also be used.  Supply the path appropriate to your own environment.
'  The PFX password should come from a secure source rather than being hard-coded.
Dim pfxPassword As String = "myPfxPassword"
Dim cert As ChilkatCert
cert.Initialize("cert")
success = cert.LoadPfxFile("qa_data/server.pfx", pfxPassword)
If success = False Then
    Log(cert.LastErrorText)
    Return
End If


'  Configure this object for server-side TLS using the certificate.  The certificate must have
'  access to its corresponding private key.
success = socket.InitSslServer(cert)
If success = False Then
    Log(socket.LastErrorText)
    Return
End If


'  Listen for connections.  Accepted connections will use TLS.
success = socket.BindAndListen(5000, 25)
If success = False Then
    Log(socket.LastErrorText)
    Return
End If


Dim connectedSock As ChilkatSocket
connectedSock.Initialize("connectedSock")
success = socket.AcceptNext(20000, connectedSock)
If success = False Then
    Log(socket.LastErrorText)
    Return
End If

Log("Accepted a TLS client connection.")
