The management policy associated with the +key is of type TSecurityPolicy. The policy can be set to +check capabilities or the Vendor ID associated with the calling process. The +calling process should have a WriteUserData capability. +

The following steps explain the process of setting a management +policy for a key:

 + +Create a file system +session using an RFs object. + + +Create an object of type CUnifiedKeyStore using CUnifiedKeyStore::NewL() or CUnifiedKeyStore::NewLC(). + + +Initialise the member functions and keystore using the asynchronous +function CUnifiedKeyStore::Initialize(). + + +List all keys in the keystore using the CUnifiedKeyStore::List() function. +Retrieve the handle of the key for which the management policy needs to be +set. + + +Set the management policy for the key using the CUnifiedKeyStore::SetManagementPolicy() function. + + +

Management policy is set for the selected key.

+Example

The following code snippet shows how to +set management policy for a key.
