Lars Schmertmann 7f77dc84fb Store QSslKey in specific key format to provide more details for key
In a TLS handshake the ephemeral server key is saved in the ssl
configuration. Clients who want to get the length or algorithm of the
key only get "Opaque" and "-1" as a result because the key is always
stored as "Opaque". This change converts the key to specific type so
more details are available and the client don't need to convert the
handle by hand.
