qmake: QT += opcua
Detailed Description▲
This class is currently available as a Technology Preview, and therefore the API and functionality provided by the class may be subject to change at any time without prior notice.
Before actually creating the singing request data, any extension needed for that specific request has to be added. Current supported extensions are SubjectAlternativeName, BasicConstrains, KeyUsage and ExtendedKeyUsage.
