* Common Name       – the common name (CN) of the CA certificate
* Issuer Name            – the CN of the issuer (= CA) of the CA certificate
* Status                       – the state of the certificate

To search for information, you can enter the search value in the appropriate field, except for **"Issuer Name"** and **"Status".**&#x20;

In the case of **"Issuer Name",** you will need to select from a dropdown box containing a list of existing CA names.

&#x20;For **"Status",** the right field will display a dropdown box with different options to select from&#x20;

&#x20;After inserting the search value or selecting the status filter, click **"Search"** to filter for all matching user certificates.

The following image shows an example of a CA-specific filter:

Each entry in the table **“Certificate Details”** represents one CA certificate.

**View:** Click on the **"View"** Icon in the Action column to view the user certificate details.

&#x20;**Download:** Click on **"Download"** Icon in the action column to download the user certificate as

* DER-encoded X.509 certificate (.cer)
* Base64-encoded X.509 certificate (.cer)
* Cryptographic Message Syntax Standard PKCS#7 certificate (.p7b)

CA Administrator can choose the preferred export format and click on the **"Download"** button to initiate the downloading process for the user certificate.

&#x20;The certificate will be saved in the usual download location of your operating system.&#x20;

If there are too many search results to display on one page, you can navigate through the pages using the navigation element at the bottom of the table.&#x20;

CA Administrator can reset the search filter by clicking on the **"Reset"** button located at the top-right of the UI.
