Use a PFX TLS Client Certificate

Demonstrates the Chilkat MailMan.SetSslClientCertPfx method, which sets the client-side certificate for SSL/TLS connections, loading it from a PFX/PKCS#12 file. The first argument is the path to the PFX file and the second is its password. This example loads a client certificate directly from a PFX.

Background: This is the convenience form of SetSslClientCert: rather than loading a Cert object first, you point straight at the PFX file and password. A PFX (PKCS#12) bundles the certificate with its private key — exactly what mutual TLS requires, since the client must prove possession of the key during the handshake. It is the usual client-credential format on Windows.
