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.

// Demonstrates the Ssh.AuthenticateSecPwPk method, which authenticates using SecureString login
// and password objects together with a private key.  The 1st argument is the username, the 2nd
// is the password, and the 3rd is an SshKey private key.

// Normally you would not hard-code the password in source.  You should instead obtain it
// from an interactive prompt, environment variable, or a secrets vault.
