While the convenient Auto PKI is the default option to install certificates on the Zoom Node and its modules, with Zoom Node, organizations can also upload their own certificates for their Zoom Node servers and modules, from the local management portal. 

If you already have a .crt file from your certificate issuer, then you can upload the file and private key directly via the local admin portal for the Node instance. However, if a CSR file and Private Key file are required to generate the certificate by your issuer, this can also be done from within the local admin portal as well.
