To upload a key file belonging to a server certificate for the communication
with the HTTPS server nginx, Node-RED, the Edge Server or the REST
API 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.
If the server certificate applies to the communication with the HTTPS server
nginx, Node-RED, the Edge Server or the REST API:
Ø Within window Certificates, select the entry key.pem below nginx.
Alternatively: If the server certificate applies to the communication with the
OPC UA-Server:
Ø Within window Certificates, select the entry key.pem below opcua.
Ê In both cases,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
appears indicating a defective file type and further processing of the key
file is terminated. For instance, this occurs if the file does not have the
extension *.pem or the contents of the file is not coded in *.pem
format. However, in case of success a security query appears whether
you really intend to replace the key file.
Ø If you are really sure not to need the current 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. After a short delay, a message is displayed
indicating that the upload has been completed and the Edge Gateway
requires a restart
