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 fso, outFile
Set fso = CreateObject("Scripting.FileSystemObject")
'Create a Unicode (utf-16) output text file.
Set outFile = fso.CreateTextFile("output.txt", True, True)

success = 0

set socket = CreateObject("Chilkat.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.
pfxPassword = "myPfxPassword"
set cert = CreateObject("Chilkat.Cert")
success = cert.LoadPfxFile("qa_data/server.pfx",pfxPassword)
If (success = 0) Then
    outFile.WriteLine(cert.LastErrorText)
    WScript.Quit
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 = 0) Then
    outFile.WriteLine(socket.LastErrorText)
    WScript.Quit
End If

'  Listen for connections.  Accepted connections will use TLS.
success = socket.BindAndListen(5000,25)
If (success = 0) Then
    outFile.WriteLine(socket.LastErrorText)
    WScript.Quit
End If

set connectedSock = CreateObject("Chilkat.Socket")
success = socket.AcceptNext(20000,connectedSock)
If (success = 0) Then
    outFile.WriteLine(socket.LastErrorText)
    WScript.Quit
End If

outFile.WriteLine("Accepted a TLS client connection.")

outFile.Close
