Set an IMAP TLS Client Certificate from a PFX File

Demonstrates the Chilkat Imap.SetSslClientCertPfx method, which supplies a TLS client certificate and private key from a PKCS #12/PFX file. The first argument is the .pfx or .p12 file path and the second is its password. Call it before connecting.

Note: The certificate path is relative to the application's current working directory. Supply the path to your own certificate file.

Background: A PFX (PKCS #12) file bundles a certificate together with its private key in a single password-protected file — the format Windows and many corporate PKI tools export. This is the counterpart to SetSslClientCertPem: use it when your credentials are packaged as one .pfx rather than as separate PEM files.
