Hello. I am using OpenSSL from within the Qt Project / QtWebEngine. The Qt Wiki says, the following Parameters are minimum recommended: no-ssl2 no-ssl3 no-idea no-mdc2 no-rc5 Since 1.0.2g, SSL2 has been removed completely. So no-ssl2 is not needed anymore. My Questions are: 1.) Are there any other Parameters that should be used? 2.) What are the Parameters for a 'Paranoid' build aka absolute Security without any comprimises? Use Case: OpenSSL get invoked by QtWebEngine automatically. There is no direct use from my side - yet. The QtWebEngine based Browser Widget is part of something like a "Software Suite": It will not replace Standard Browser like Firefox. Everything older than TLS 1.0 should not be supported. This Software Suite is used 99 Percent on private PCs and not in a Enterprise Environment. But it must still be secure as possible to transceive Personal Data (i.e. Database Entries), Chat etc. Project is in "Alpha" State - there is no VServer or something similar yet to concentrate Communication etc. The (OpenSSL)Server Setup will be based on what you Experts have to say. Environment: Under Windows 7 to Windows 10: CygWin / MSVC 2015 (compilation done under Win10). Under Antergos Linux (KDE): GCC 4.9.2 (not tested yet if Qt can be built with GCC >=5.x as the Qt Framework is 4.9.x based). Thank You for your Time! And please forgive me my horrible english :) Oliver -------------- next part -------------- A non-text attachment was scrubbed...
