Generating Subsystem CSR with PKI NSS - dogtagpki/pki GitHub Wiki
To create a certificate request, prepare a certificate extension configuration (e.g. subsystem.conf):
authorityKeyIdentifier = keyid:always keyUsage = critical, digitalSignature, nonRepudiation, keyEncipherment, dataEncipherment extendedKeyUsage = clientAuth
Then execute the following command:
$ pki nss-cert-request \ --subject "CN=Subsystem Certificate" \ --ext subsystem.conf \ --csr subsystem.csr
