Set an FTPS Client Certificate from a PFX File

Demonstrates the Chilkat Ftp2.SetSslClientCertPfx method, which loads a client certificate and private key from a PFX/P12 file. The first argument is the file path and the second is its password.

Note: The local paths are relative to the application's current working directory. Absolute paths may also be used. Supply the paths appropriate to your own environment.

Background: A PFX (PKCS #12) file bundles a certificate with its private key in one password-protected file — the format Windows and many corporate PKI tools export. This is the counterpart to SetSslClientCertPem for mutual-TLS authentication when your credentials are packaged as a single .pfx. Set it before connecting.
