Detailed Description

template<typename ReqT, typename RespT = Traits::EmptyType>
class vlink::SecurityServer< ReqT, RespT >

Convenience alias for Server with message security enabled.

Equivalent to Server<ReqT, RespT, SecurityType::kWithSecurity>. Each incoming request is decrypted before dispatch to the callback, and each outgoing response is encrypted before transmission.

Template Parameters

ReqT	Request type.
RespT	Response type (defaults to Traits::EmptyType).
