An application should make appropriate calls for NanoSec IKE configuration and customization. The following calls should typically be placed after the call made to IKE_init during *NanoSec IKE Integration*:

- `IKE_ikeSettings` To customize the application’s IKE callbacks and dynamically adjust IKE configuration.
- `IKE_initServer` To register an IKE pre-shared key and/or a host key-certificate pair. If both a pre-shared key and host key-certificate pair are provided, the certificate has a higher priority during negotiation than the pre-shared key.
