Oracle 10g Enabling Certificate Revocation Status Checking on the Client

You would use the following procedure to enable CRL checking on the client side:

  1. Start the oracle Net Manager GUI, go to the SSL tab of the Oracle Advanced Security window, and select Configure SSL for: Client.

  2. Select one of the following options from the Revocation Check list. Specifying a value for this field outs the ssl_cert_revocation parameter in the sqlnet.ora file. The values allowed are:

  • REQUIRED -- Setting the field to REQUIRED mandates certificate revocation status checking. The SSL connection will be rejected if a certificate is revoked or no CRL is found. In REQUIRED mode, SSL connections are accepted only if it can be verified that the certificate has not been revoked.

  • REQUESTED -- Setting the field to REQUESTED performs certificate revocation status checking if a CRL is available. The SSL connection is rejected only if a certificate is revoked. SSL connections are accepted if either no CRL is found or the certificate has not been revoked.

  • Setting the ssl_cert_revocation parameter to either REQUIRED or REQUESTED will enable certificate revocation status checking. By default, the system searches for CRLs first in the local file system, then Oracle Internet Directory, and finally in the certificate’s CRL DP extension.

  1. Choose File > Save Network Configuration. The sqlnet.ora file is updated with the appropriate value for ssl_cert_revocation.
