Socket TLS Mutual Authentication (Client-Side Certificate)

See more Socket/SSL/TLS Examples

This example demonstrates how to provide a client-side certificate, also known as "two-way authentication" or "mutual authentication" for servers that require a client certificate. PowerBuilder

integer li_rc
integer li_Success
oleobject loo_Sock
integer li_BTls
integer li_Port
integer li_MaxWaitMs

li_Success = 0

// This example assumes the Chilkat API to have been previously unlocked.
// See Global Unlock Sample for sample code.

loo_Sock = create oleobject
li_rc = loo_Sock.ConnectToNewObject("Chilkat.Socket")
if li_rc < 0 then
    destroy loo_Sock
    MessageBox("Error","Connecting to COM object failed")
    return
end if

// Set the certificate to be used for mutual TLS authentication
// (i.e. sets the client-side certificate for two-way TLS authentication)
li_Success = loo_Sock.SetSslClientCertPfx("/home/bob/pfxFiles/myClientSideCertWithPrivateKey.pfx","pfxPassword")
if li_Success <> 1 then
    Write-Debug loo_Sock.LastErrorText
    destroy loo_Sock
    return
end if

// Note: The certificate used for the client-side of TLS mutual authentication
// must have the associated private key available. (.pfx/.p12 files typically store both
// the certificate and associated private key.)

// Establish the connection using the socket object (with client certificate authentication).

    Write-Debug "Connect Failure Error Code: " + string(loo_Sock.ConnectFailReason)
    Write-Debug loo_Sock.LastErrorText
