Add Host Key Validation #7
Description
By default, the ssh2 automatically accepts any server-key. In secure environments it can be desired to implement the hostVerifier callback function, to identify the server host blocking potential man-in-the-middle attacks. The ask would be, to use the ~/.ssh/known_hosts file for validation.
In the case the node is unknown or the host-key has changed, a pop-up dialogue would inform the user allowing to accept the new key and to update the known_hosts or to block the connection.
