encrypted with a private key is decrypted with its public key. For example, party A encrypts its certificate with its private key and sends it to party B. Party B decrypts the certificate with party A’s public key.

Obtaining a Server Certificate

Best practices is to replace the default server certificate in the controller with a custom certificate issued for your site or domain by a trusted CA. To obtain a security certificate for the controller from a CA:

1.Generate a Certificate Signing Request (CSR) on the controller using either the WebUI or CLI.

2.Submit the CSR to a CA. Copy and paste the output of the CSR into an email and send it to the CA of your choice.

3.The CA returns a signed server certificate and the CA’s certificate and public key.

4.Install the server certificate, as described in "Importing Certificates" on page 637.

NOTE: There can be only one outstanding CSR at a time in the controller. Once you generate a CSR, you need to import the CA- signed certificate into the controller before you can generate another CSR.

In the WebUI

1.Navigate to the Configuration > Management > Certificates > CSR page.

2.Enter the following information:
