Recommended configuration procedure for manual request
Step Remarks
1. Creating a PKI entity
Required.
Create a PKI entity and configure the identity information.
A certificate is the binding of a public key and the identity information of
an entity, where the distinguished name (DN) shows the identity
information of the entity. A CA identifies a certificate applicant uniquely
by an entity DN.
The DN settings of an entity must be compliant to the CA certificate issue
policy. Otherwise, the certificate request might be rejected. You must
know the policy to determine which entity parameters are mandatory or
optional.
2. Creating a PKI domain
Required.
Create a PKI domain, setting the certificate request mode to Manual.
Before requesting a PKI certificate, an entity needs to be configured with
some enrollment information, which is called a PKI domain.
A PKI domain is intended only for convenience of reference by other
applications like IKE and SSL, and has only local significance.
3. Generating an RSA key pair
Required.
Generate a local RSA key pair.
By default, no local RSA key pair exists.
Generating an RSA 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, and the public key is transferred to the CA along with
some other information.
IMPORTANT:
If a local certificate already exists, remove the certificate before generating
a new key pair to keep the consistency between the key pair and the local
certificate.
4. Retrieving the CA certificate
Required.
Obtain the CA certificate and save it locally. For more information, see
"
Retrieving and displaying a certificate ."
Certificate retrieval serves the following purposes:
• Locally store the certificates associated with the local security domain
for improved query efficiency and reduced query count,
• Prepare for certificate verification.
IMPORTANT:
If a local CA certificate already exists, you cannot perform the CA
certificate retrieval operation. This helps avoid possible mismatch between
certificates and registration information resulting from relevant changes. To
retrieve the CA certificate, you must remove the CA certificate and local
certificate first.
