![]() Select (highlight) that new server certificate and press the ‘Cert Request’ button to create a new certificate signing request (‘.csr’ file). After completing the creation of the Server Certificate you then must sign this certificate using the CA previously created.Use that for the ‘Common Name’ and the ‘Alternative Server Name’ in the server certificate. An example: Open 'System' on the computer and locate the 'Full computer name'. Be aware that Niagara versions prior to version N4.8 must use the Fully Qualified Computer Name due to a problem using IP addresses. Meaning, the IP address could be used as the ‘Common Name’ and the ‘Fully Qualified Computer Name’ could be used as the ‘Alternative Server Name’. These two entries are not required to match. Note that Niagara automatically copies the first item in the list of the ‘Common Name’ over to the “Alternative Server Name’. The ‘Common Name’ and the ‘Alternative Server Name’ need to be entered. Next using the Niagara Station’s Certificate Manager (Same tool can be accessed under Platform Services or in Platform) create a new Server Certificate.Make sure you remember the CA’s password which is needed when you sign certificates using the CA. The ‘Alias’ and ‘Common Name’ usually match and can be whatever name desired, making sure there are no spaces or special characters in the name. The CA will reside in the Workbench User Key Store. Using the Workbench Certificate Manager, create a CA that will be used to sign server certificates.If you are creating a Server Certificate for a station then you want to use that station’s Certificate Manager. If you are creating a CA that will be used for certificate signing you’ll want to use the Workbench Certificate Manger. Make sure you are in the correct Certificate Manager when creating a Certificate Authority (CA) or Server Certificate. While working with the " Niagara Certificate Management" tool, all files created can be saved to the default ‘Cert Management’ folder that is created in the Niagara User Home. These values are called Subject Alternative Names (SANs) ![]()
