Configuring OCSP Certificate Status

Configuring Online Certificate Status Protocol (OCSP) involves adding an OCSP responder, binding the OCSP responder to a signed certificate from a Certificate Authority (CA), and binding the certificate and private key to a Secure Sockets Layer (SSL) virtual server. If you need to bind a different certificate and private key to an OCSP responder that you already configured, you need to first unbind the responder and then bind the responder to a different certificate.

To configure OCSP

1. On the Configuration tab, in the navigation pane, expand SSL and then click OCSP Responder.

2. In the details pane, click Add.

3. In Name, type a name for the profile.

4. In URL, type the web address of the OCSP responder.

   This field is mandatory. The Web address cannot exceed 32 characters.

5. To cache the OCSP responses, click Cache and in Time-out, type the number of minutes that NetScaler Gateway holds the response.

6. Under Request Batching, click Enable.

7. In Batching Delay, specify the time, in milliseconds, allowed for batching a group of OCSP requests.

   The values can be from 0 through 10000. The default is 1.

8. In Produced At Time Skew, type the amount of time NetScaler Gateway can use when the appliance needs to check or accept the response.

9. Under Response Verification, select Trust Responses if you want to disable signature checks by the OCSP responder.

   If you enable Trust Responses, skip Step 8 and Step 9.

10. In Certificate, select the certificate that is used to sign the OCSP responses.

    If a certificate is not selected, the CA that the OCSP responder is bound to is used to verify responses.

11. In Request Time-out, type the number of milliseconds to wait for an OCSP response.

    This time includes the Batching Delay time. The values can be from 0 through 120000. The default is 2000.

12. In Signing Certificate, select the certificate and private key used to sign OCSP requests. If you do not specify a certificate and private key, the requests are not signed.

13. To enable the number used once (nonce) extension, select Nonce.

14. To use a client certificate, click Client Certificate Insertion.

15. Click Create and then click Close.
