# Search

The CA Administrator can search for all types of user certificates, including individual, device, code signing, and document signer certificates, etc. This can be done in any non-CA and non-role owner certificate group within the emCA database.

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

**View Certificate:** To access user certificate details, simply click on the **"View"** icon.

**Download:** Click on the **"Download"** icon to download the certificate as: &#x20;

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

Select your preferred export format and click **"Download"** to start downloading your user certificate to the standard OS location.

In case there are too many search results to fit on one page, you can navigate through the pages by using the pagination feature located at the bottom of the table.

Simply click on the "**Reset"** button located in the top-right corner of the UI to clear the search filter.
