<pre style="white-space: pre-wrap; white-space: -moz-pre-wrap; white-space: -pre-wrap; white-space: -o-pre-wrap; word-wrap: break-word;">Your implementation works, but looking at the code I feel that the architecture and design is not that good. If you end up with lines like this "link->provider()->pairingHandler()->acceptPairing(this);", it is probably a sign that is telling you that things are not where they should be. The task of refactor doesn't seem well done. I would ask that, now that you have more knowledge of the code, you have a look at my coments and see if you can come up with a better architecutre, organizing things a bit better. For now I only had a look at the code, next week I will test and give you more feedback, but in the meanwhile I would like you to try to reorganize the code a bit.</pre>

<pre style="white-space: pre-wrap; white-space: -moz-pre-wrap; white-space: -pre-wrap; white-space: -o-pre-wrap; word-wrap: break-word;">I think the timeout should be part of the pairing handler. Other pairing mechanisms might not have a timeout or have a shorter/longer one (eg: 24hours to accept pairing through a cloud server). Actually, the status "Requested" and "RequestedByPeer" should be known only by the PairingHandler. The Device class should only care about Paired/NotPaired.</pre>

PS: Actually I see that you already started doing that with setDeviceProperty and getDeviceProperty, even though you never used it. That seems a better approach than this.</pre>

<li style="padding: 0;text-rendering: inherit;margin: 0;line-height: inherit;white-space: normal;">Similar to Android version, this SSL implementation supports old version also.</li>
<li style="padding: 0;text-rendering: inherit;margin: 0;line-height: inherit;white-space: normal;">Certificate is generated when public key is generated using QCA, but used as QSslCertificate because QSslSocket don't like QCA certificate.</li>
<li style="padding: 0;text-rendering: inherit;margin: 0;line-height: inherit;white-space: normal;">A new server is written overriding QTcpServer for setting socket descriptor to QSslSocket.</li>
<li style="padding: 0;text-rendering: inherit;margin: 0;line-height: inherit;white-space: normal;">QSslSocket works as plain socket to transfer identity package and then either uses encrypted mode or normal mode according to the received package.</li>
<li style="padding: 0;text-rendering: inherit;margin: 0;line-height: inherit;white-space: normal;">If connetion is to be on SSL, new link is only added after successful handshake.</li>
<li style="padding: 0;text-rendering: inherit;margin: 0;line-height: inherit;white-space: normal;">Certificate is embedded into identity package on start of encrypted mode and then set in device using it.</li>
<li style="padding: 0;text-rendering: inherit;margin: 0;line-height: inherit;white-space: normal;">PairingHandler is added like in Android version so that each LinkProvider manage pairing according to its own rules.</li>
