Well, yes, please, otherwise I'll do it myself 😊 > If NO: Then who will write it? When? I will, 5.11. > Then what module should it be in? Option 'a' is optimal. ________________________________ From: Development <development-bounces+timur.pocheptsov=qt...@qt-project.org> on behalf of Thiago Macieira <thiago.macie...@intel.com> Sent: Friday, August 18, 2017 8:57:09 PM To: development@qt-project.org Subject: [Development] DTLS support in Qt Hello Last year at QCS, I joined the Networking discussions and one of my requests was DTLS support. Everything else needed to support IoT was already in place, in flight (the QNetworkDatagram class) or I could do it myself (new API for QNetworkInterface coming soon). DTLS was the only thing I wasn't allowed to contribute and no one else has stepped up in the last year. So I decided to implement it myself. I've now got a proof of concept to support DTLS over QUdpSocket and it already manages to connect one client and server, verify the certificate (haven't tested failure) and communicate with itself, with the "openssl" binary and with "gnutls-serv" binary. I've got approval from Intel to contribute it. I'd like Qt to have DTLS support. Should *I* contribute it? This question is important because there used to be restrictions on "US persons" contributing cryptography-related code. I need an answer from the Qt Project. If NO: Then who will write it? When? Can you finish it by Qt 5.11 feature freeze? If YES: Then what module should it be in? a) QtNetwork Would be ideal, as there are quite a few changes to QSslSocketBackend, QSslContext, etc. that are required. We'd also reuse the dynamic OpenSSL loading. If I can implement DTLS support in QtNetwork, I can make these changes myself. b) another module, outside of qtbase This module would be licenced LGPLv3, no commercial. Not ideal, but workable. The changes I mentioned above would still need to be implemented, so we'd need a volunteer to implement them and work with me. It shouldn't be too difficult. c) not in Qt Really not ideal. Would make for a crappy API and would increase the development time at least threefold, probably more. I'll be really disappointed if the answer is "no, we won't accept this contribution and we won't develop it for 5.11 either". -- Thiago Macieira - thiago.macieira (AT) intel.com Software Architect - Intel Open Source Technology Center _______________________________________________ Development mailing list Development@qt-project.org http://lists.qt-project.org/mailman/listinfo/development
