Keystore Overview</title><shortdesc>The Unified Keystore provides a unified view of all the keystores
in a device.</shortdesc><prolog><metadata><keywords/></metadata></prolog><conbody>
<section><title>Introduction</title> <p>The Unified Keystore provides an interface
to access keys in various keystore implementations in the device. Symbian
provides a default keystore implementation. Device creators may include Symbian's
keystore implementation in a device and may add their own keystores. </p> </section>
<section id="GUID-9DD8C1BF-A106-5E77-88A3-43A94AB68335"><title>Keystore functionality</title> <p>The
Unified Keystore API provides the following functionality: </p> <ul>
<li id="GUID-3447C46E-8AD1-577F-9B92-808FD92C91DA"><p>Generate keys </p> </li>
<li id="GUID-FF0A58FD-9210-52CA-A10F-EBB12AF559E0"><p>List Keystores </p> </li>
<li id="GUID-2DC65FE5-A070-518B-BDA5-481E40D7351D"><p>Import keys </p> </li>
<li id="GUID-DC9B0CC5-2219-5913-B93A-5443E1F8FE4E"><p>Export keys </p> </li>
<li id="GUID-BECC7117-3B1E-574C-ADE1-D03C4FABB2E3"><p>List keys </p> </li>
<li id="GUID-BC1658CB-043E-54AB-BD74-202E67B65D05"><p>Delete keys </p> </li>
<li id="GUID-3B6A82DD-523F-500E-8C52-731EF0AEC278"><p>Sign keys </p> </li>
</ul> <p>These tasks are performed differently depending on the keystore version
being used. </p> <p>The Symbian keystore supports access control to the keystore
using application UIDs. There are two modes of access:</p><ul>
<li><p>Owner: As key owners, applications can create, delete and manage keys. </p></li>
<li><p>User: As key users, application can view and retrieve keys but cannot
perform any modification operations.</p></li>
</ul> <p> <b>Notes:</b>  </p> <ul>
