\class QOpcUaX509CertificateSigningRequest
\inmodule QtOpcUa
\since 5.14
\brief QOpcUaX509CertificateSigningRequest create a certificate signing request
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.
