Exporting an Identity Certificate

The Cisco Mobility Advantage Proxy, Cisco Presence Federation Proxy, or Cisco Intercompany Media Engine Proxy require that you export the ASA identity certificate to install on the Cisco Mobility Advantage server, Cisco Presence Federation server, and Cisco Unified Communications server, respectfully.

You use the wizard to export a self-signed identity certificate. The identity certificate has all associated keys and is in PKCS12 format, which is the public key cryptography standard. When configuring a Unified Communications proxy by using the wizard, you click the Generate and Export ASA’s Identify Certificate button while in the local-side or server-side certificate management step of the wizard. The Export certificate dialog box appears.

From the Export certificate dialog box, perform these steps:

Step 1 Enter the name of the PKCS12 format file to use in exporting the certificate configuration. Alternatively, click Browse to display the Export ID Certificate File dialog box to find the file to which you want to export the certificate configuration.

Step 2 Click Export Certificate to export the certificate configuration.

An information dialog box appears informing you that the certificate configuration file has been successfully exported to the location that you specified.

You complete the configuration of the Cisco Mobility Advantage Proxy, Cisco Presence Federation Proxy, or Cisco Intercompany Media Engine Proxy, you must import the generated ASA identify certificate in to the Cisco Mobility Advantage server, Cisco Presence Federation server, and Cisco Unified Communications server, respectfully, depending on which proxy you are configuring.

See the documentation for the for each of these products for information about importing an identity certificate into each.
