– UCF uses XML Encryption to provide a framework for encryption, allowing a variety of algorithms to be used.
– Even though a UCF container MAY contain non-XML data, XML Encryption can be used to encrypt all data in a UCF container
– Signed resources MAY subsequently be encrypted by using the Decryption Transform for XML Signature. This feature enables an application such as a UCF agent to distinguish data that was encrypted before signing from data that was encrypted after signing.
