org.apache.xml.security.keys.keyresolver.KeyResolverSpi

org.apache.xml.security.keys.keyresolver.implementations.EncryptedKeyResolver

public class EncryptedKeyResolver
extends KeyResolverSpi

The EncryptedKeyResolver is not a generic resolver. It can only be for specific instantiations, as the key being unwrapped will always be of a particular type and will always have been wrapped by another key which needs to be recursively resolved. The EncryptedKeyResolver can therefore only be instantiated with an algorithm. It can also be instantiated with a key (the KEK) or will search the static KeyResolvers to find the appropriate key.
