All Implemented Interfaces:

EncryptedKeyResolver

public class SimpleRetrievalMethodEncryptedKeyResolver
extends AbstractEncryptedKeyResolver

Implementation of EncryptedKeyResolver which finds EncryptedKey elements by dereferencing RetrievalMethod children of the KeyInfo of the EncryptedData context. The RetrievalMethod must have a Type attribute with the value of EncryptionConstants.TYPE_ENCRYPTED_KEY. The URI attribute value must be a same-document fragment identifier (via ID attribute). Processing of transforms children of RetrievalMethod is not supported by this implementation.
