Keystores</title><shortdesc>This section explains how to retrieve keystore implementations. </shortdesc><prolog><metadata><keywords/></metadata></prolog><taskbody>

<context><p>Keystores can be used in manager mode or user mode. In manager

mode, modifications to an existing keystore can be performed through the <xref href="GUID-89FFDC49-F722-3A68-8601-C461AD2FBDF2.dita"><apiname>MCTKeyStoreManager</apiname></xref> interface.

In user mode, a keystore can be viewed using the <xref href="GUID-2B3202F8-469D-3253-90E8-B553506AD47A.dita"><apiname>MCTKeyStore</apiname></xref> interface. </p><p> The
