Re: [Interest] displaying Qt-coded JPEG image in browser

Re: [Interest] server certificate integration
hi, why not simply read certificate related stuff from file/env and add proper configuration using https://doc.qt.io/qt-6/qsslconfiguration.html and when expiration is about to happen, reload the whole and configure again? regards, alex On 26.02.2024 16:11, Alexander Carôt via Interest wrote: Hi all, I have a secure websocket server based on the Qt example: https://doc.qt.io/qt-6/qtwebsockets-sslechoserver-example.html It requires a certificate and a key which are compiled into the server and it functions well. However, whenever the certificate expires (such as Let’s encrypt after 90 days) I need to recompile the server with the renewed certificate. In order to avoid this process I wonder if it is possible to somehow externally point to the the new certificates without integration at compilation time.
