<p> XML Security Library has a built-in simple keys store
implemented using a keys list. You can use it in your application
if you have a small number of keys. However, this might be not a
best option from performance point of view if you have a lot of keys.
In this case, you probably should implement your own keys store
using an SQL database or some other keys storage.
