All of the endpoints in the ssh client library require a credential resource. The resource must be transreptable to
the following form...
The tag is the name of the user to login on the remote SSH server.
The tag is either the password for the user (if password auth is being used) or is the password of the private key (if PKI auth is being used). If a private key
has no password this field is ignored.
If the remote host supports PKI authentication then the resource specified in the privateKeyURI is SOURCEd in the ROC domain. This resource must be the private
key of the ssh server connection.
