Structure SilcSKEStruct NAME
        struct SilcSKEStruct { ... };
DESCRIPTION
        This structure is the SKE session context, and has a type definition
        to SilcSKE. The structure includes the network connection socket,
        securit properties collected during the SKE negotiation, payloads
        sent and received during the negotiation, and the actual raw key
        material too. The application usually does not need to reference
        to the inside of this structure.  However, checking the current
        status of the session can easily be checked with ske->status.
