# Copying Keystore Entries in Edge Integration Cell
The Keystore Monitor allows a tenant administrator to manage the tenant keystore and its entries \(X.509 certificates and key pairs\).
> ### Note:
> For details on the list view as well as on how to create, add, or upload security artifacts, see: [Managing Keystore Entries](https://help.sap.com/docs/integration-suite/sap-integration-suite/managing-keystore-entries?version=CLOUD&q=keystore).
> ### Note:
> You can assign a runtime to one keystore only, but you can assign a keystore to several runtimes. If you assign only one runtime to an exiting keystore, this keystore is only available for this single runtime.
>
> Remember:
>
> - The maximum size of a keystore assigned to an edge runtime is 1 MB.
>
> - The maximum number of keystores is limited to 20 per tenant.
>
> - You can assign up to 20 runtimes to a keystore.
> ### Caution:
> To change the existing assignment of a keystore to a specific runtime, can cause message processing failures.
