Set a TLS Client Certificate from a Cert Object

See more Socket/SSL/TLS Examples

Demonstrates Socket.SetSslClientCert, which configures a certificate as the client certificate for subsequent TLS connections. The certificate must have access to its private key.

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 Long
success = 0

Dim socket As New ChilkatSocket

'  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
pfxPassword = "myPfxPassword"
Dim cert As New ChilkatCert
success = cert.LoadPfxFile("qa_data/client.pfx",pfxPassword)
If (success = 0) Then
    Debug.Print cert.LastErrorText
    Exit Sub
End If

'  Configure the client certificate before connecting.  Use this only when the server requests or
'  requires client-certificate authentication (mutual TLS).
success = socket.SetSslClientCert(cert)
If (success = 0) Then
    Debug.Print socket.LastErrorText
    Exit Sub
End If

Dim bTls As Long
bTls = 1
Dim maxWaitMs As Long
maxWaitMs = 5000
success = socket.Connect("example.com",5000,bTls,maxWaitMs)
If (success = 0) Then
    Debug.Print socket.LastErrorText
    Exit Sub
End If

Debug.Print "Connected with mutual TLS."
