To upload a key file for client authorization for a specific server from a file
into the Edge Gateway, proceed as follows:
Ø Select option Service certificates within selection list (Selection list for
certificate type [} page 79]).
Ê Within window Certificates, a tree structure is displayed instead of the
list of preinstalled trustworthy certificates.
Ø In window Certificates, select the entry node-
opcuaclient_key.pem below node-red.
Ê The window Certificate Viewer is empty now (Text No data).
Ø Click at button Upload in the header of window Certificates.
Ê A file selection dialog appears.
Ø Within that dialog, select the key file to be uploaded! This file must be
present in the *.pem file format [} page 248].
Ê The key file is checked for correctness. In case of error, a message
indicating a defective file type is displayed and further processing of the
key file is terminated. For instance, this occurs if the file does not have
the extension *.pemor the contents of the file is not coded in *.pem
format. However, in case of success a confirmation prompt whether you
really intend to replace the key file is displayed.
Ø If you are really sure not to need the currently stored key file any longer,
click at Yes.
ð The selected key file is uploaded into the Edge Gateway. During this,
the formerly existing key within the Edge Gateway is irreversibly
destroyed. Thus, there is no possibility to restore this key if no suitable
backup is available. A message is displayed indicating that the upload
has been completed and the Edge Gateway requires a restart.
