Create a Server Certificate and Signing Request
Summary
Use this procedure if your company or agency has its own Certificate
Authority or if you plan to use a commercial Certificate Authority to
sign your server certificates.
• Create a Certificate Signing Request (CSR).The CSR contains all the
information for a server certificate except the digital signature. This
process creates two output files:
– The file with the .p15 extension contains the Management Card’s
private key.
– The file with the .csr extension contains the certificate signing
request, which you send to an external Certificate Authority.
• When you receive the signed certificate from the Certificate Authority,
import that certificate. Importing the certificate combines the .p15 file
containing the private key and the file containing the signed certificate
from the external Certificate Authority. The output file is a new
encrypted server certificate file with a .p15 extension.
• Load the server certificate onto the Management Card in the Battery
Management System master controller.
• For each Management Card that requires a server certificate, repeat
the tasks that create and load the server certificate.
