SSH Authenticate with Password and Private Key

Demonstrates the Chilkat Ssh.AuthenticatePwPk method, which authenticates with a server that requires both a password and a private key. The first argument is the username, the second is the password, and the third is an SshKey private key.

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

Background: Most servers require either a password or a public key, not both — but some high-security configurations mandate multi-factor SSH, combining something you know (the password) with something you have (the key). This method satisfies that policy in one call. As always, the password should come from a secure source rather than a literal in code.
