Authenticate an SSH Tunnel with a Password

See more Socket/SSL/TLS Examples

Demonstrates Socket.SshAuthenticatePw, which authenticates an SSH tunnel session using a login and password. Call SshOpenTunnel first.

Background. Authenticate before opening forwarded channels. The password should come from a secure source and never be logged; public-key authentication is often preferred.
