A simple application that establishes DTLS connection(s) and sends/receives datagrams. Class DtlsAssociation is essentially a QUdpSocket|QDtls pair: it initiates a handshake, handles timeouts and errors. After establishing an encrypted connection it sends messages to the server and processes responses. Task-number: QTBUG-67596 Change-Id: I92d481b7dfd2459e6a93c754b338a2e897a7feaf Reviewed-by: Timur Pocheptsov <timur.pocheptsov@qt.io>
