SFTP Authenticate with a SecureString Password and Private Key

See more SFTP Examples

Demonstrates the Chilkat SFtp.AuthenticateSecPwPk method, which authenticates using SecureString login and password objects together with a private key. 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.
