// See Global Unlock Sample for sample code.

// Load any type of certificate (.cer, .p7b, .pem, etc.) by calling LoadFromFile.

    release loHttp
    release loCert

// Load the private key.
loBd = createobject("CkBinData")

    release loHttp
    release loCert
    release loPrivKey
    release loBd

// Associate the private key with the cert.

if (llSuccess <> .T.) then
    ? loCert.LastErrorText
    release loHttp
    release loCert
    release loPrivKey
    release loBd
    return
endif

// Set the certificate to be used for mutual TLS authentication
// (i.e. sets the client-side certificate for two-way TLS authentication)
llSuccess = loHttp.SetSslClientCert(loCert)
if (llSuccess <> .T.) then
    ? loHttp.LastErrorText
    release loHttp
    release loCert
    release loPrivKey
    release loBd
    return
endif

// At this point, the HTTP object instance is setup with the client-side cert, and any SSL/TLS
// connection will automatically use it if the server demands a client-side cert.
