The CA certificate in the PKI domain is used to verify the authenticity and validity of a local certificate.
Generating a key pair is an important step in certificate request. The key pair includes a public key and
a private key. The private key is kept by the user. The public key is transferred to the CA along with some
other information. For more information about RSA key pair configuration, see
Configuration guidelines
If a PKI domain already has a local certificate, creating an RSA key pair might result in
•
inconsistency between the key pair and the certificate. To generate a new RSA key pair, delete the
local certificate and then execute the public-key local create command (see Security Command
Reference).
A newly created key pair will overwrite the existing one. If you perform the public-key local create
•
command in the presence of a local RSA key pair, the system will ask you whether you want to
overwrite the existing one.
If a PKI domain already has a local certificate, you cannot request another certificate for it. This
•
helps avoid inconsistency between the certificate and the registration information resulting from
configuration changes. Before requesting a new certificate, use the pki delete-certificate command
to delete the existing local certificate and the CA certificate stored locally.
•
When it is impossible to request a certificate from the CA through SCEP, you can print the request
information or save the request information to a local file, and then send the printed information or
saved file to the CA by an out-of-band means. To print the request information, use the pki
request-certificate domain command with the pkcs10 keyword. To save the request information to
a local file, use the pki request-certificate domain command with the pkcs10 filename filename
option.
Make sure the clocks of the entity and the CA are synchronous. Otherwise, the validity period of the
•
certificate will be abnormal.
The configuration made by the pki request-certificate domain command is not saved in the
•
configuration file.
