SSH Authenticate with a SecureString Password and Private Key

See more SSH Examples

Demonstrates the Chilkat Ssh.AuthenticateSecPwPk method, which performs the same combined password/private-key authentication as AuthenticatePwPk but receives the username and password as SecureString objects. The third argument is the 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.
