DefaultDelegateProvider (IAIK PKCS#11 Provider API Documentation)

  - - iaik.pkcs.pkcs11.provider.DefaultDelegateProvider

```
public class DefaultDelegateProvider
extends DelegateProvider
```
This is the default implementation of the delegate provider. It is used as default for the global delegate provider and the providers' delegate providers. This implementation can be configured using the iaik/pkcs/pkcs11/provider/DefaultDelegateProvider.properties. If the configured provider is no valid delegate (e.g. it is also a PKCS#11 provider), this implementation uses the IAIK provider (name IAIK).
