Configuration task list for requesting a certificate manually
Task Remarks
Creating a PKI
Entity
Required
Create a PKI entity and configure the identity information.
A certificate is the binding of a public key and an entity, where an entity is the
collection of the identity information of a user. A CA identifies a certificate
applicant by entity.
The identity settings of an entity must be compliant to the CA certificate issue
policy. Otherwise, the certificate request may be rejected.
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 referred to as a PKI domain.
A PKI domain is intended only for convenience of reference by other
applications like SSL, and has only local significance.
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,
while the public key is transferred to the CA along with some other information.
If there is already a local certificate, you need to remove the certificate before
generating a new key pair, so as to keep the consistency between the key pair
and the local certificate.
Retrieving the CA
certificate
Required
Certificate retrieval serves two purposes:
z
Locally store the certificates associated with the local security domain for
improved query efficiency and reduced query count,
z
Prepare for certificate verification.
If there are already CA certificates locally, you cannot perform the CA
certificate retrieval operation. This is to avoid possible mismatch between
certificates and registration information resulting from relevant changes. To
retrieve the CA certificate, you need to remove the CA certificate and local
certificate first.
