Configuring the OpenCA server
The configuration is not shown. For information about how to configure an OpenCA server, see related
manuals.
When you configure the CA server, use the OpenCA version later than version 0.9.2 because the earlier
versions do not support SCEP.
Configuring the device
1. Synchronize the device's system time with the CA server for the device to correctly request
certificates. (Details not shown.)
2. Create an entity named aaa with the common name as rnd, the country code as CN, the
organization name as test, and the unit name as software.
<Device> system-view
[Device] pki entity aaa
[Device-pki-entity-aaa] common-name rnd
[Device-pki-entity-aaa] country CN
[Device-pki-entity-aaa] organization test
[Device-pki-entity-aaa] organization-unit software
[Device-pki-entity-aaa] quit
3. Configure a PKI domain:
# Create a PKI domain named openca and enter its view.
[Device] pki domain openca
# Specify the name of the trusted CA as myca.
[Device-pki-domain-openca] ca identifier myca
# Configure the certificate request URL. The URL is in the format http://host/cgi-bin/pki/scep,
where host is the host IP address of the OpenCA server.
[Device-pki-domain-openca] certificate request url
http://192.168.222.218/cgi-bin/pki/scep
# Configure the device to send certificate requests to ra.
[Device-pki-domain-openca] certificate request from ra
# Specify the PKI entity name as aaa.
[Device-pki-domain-openca] certificate request entity aaa
# Specify the RSA key pair with the purpose general, the name abc, and the length 1024 bits.
[Device-pki-domain-openca] public-key rsa general name abc length 1024
[Device-pki-domain-openca] quit
4. Generate a local RSA key pair.
[Device] public-key local create rsa name abc
The range of public key size is (512 ~ 2048).
If the key modulus is greater than 512,it will take a few minutes.
