Set a TLS Client Certificate from a PFX

See more Socket/SSL/TLS Examples

Demonstrates Socket.SetSslClientCertPfx, which loads and configures a TLS client certificate and private key from a PFX/P12 file.

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"

'  Load and configure the TLS client certificate and private key from a PFX/P12 file.  Configure the
'  client certificate before connecting.
success = socket.SetSslClientCertPfx("qa_data/client.pfx",pfxPassword)
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."
