== Manual installation ==
One can add server certificates to the {{UBIK Android}} application ({{Version/AndroidSince|2.3.1}}) in addition to the pre-installed certificates, using a button in the '''Info Activity'''.
This means you can copy this keystore and reuse it on another device by pasting it there!
{{Attention|The certificate has to be provided as *.cer file}}
{{Attention|A file browser app has to be installed on your device in order to select the certificate file from the SD-card.}}
== Automatic Import ==
One can place certificate files in a predefined folder in order for them to be imported automatically when the app ({{Version/AndroidSince|2.5.1}}) starts up the next time.
The folder depends on the app:
<pre>
<sd-card>/Android/data/com.augmensys.ubik.<custom_app>/files/cert
</pre>
== Certificate list ==
In the Info activity ({{Version/AndroidSince|2.5.1}}), there is a button labelled "Show certificates" that opens a list of all installed certificates, displaying their subject and expiry date.
{{Attention|The certificate has to be provided as a X.509 DER encoded file, e.g. *.cer}}
{{Hint|The certificate will remain on the device even if the application is reinstalled.}}
