Interface CipherReference

- All Known Implementing Classes:
XMLCipher.Factory.CipherReferenceImpl
public interface CipherReference
CipherReference
identifies a source which, when processed, yields the encrypted octet sequence.The actual value is obtained as follows. The
CipherReference URI
contains an identifier that is dereferenced. Should the Transforms, the data resulting from dereferencing theURI
is transformed as specified so as to yield the intended cipher value. For example, if the value is base64 encoded within an XML document; the transforms could specify an XPath expression followed by a base64 decoding so as to extract the octets.The syntax of the
URI
and Transforms is similar to that of [XML-DSIG]. However, there is a difference between signature and encryption processing. In [XML-DSIG] both generation and validation processing start with the same source data and perform that transform in the same order. In encryption, the decryptor has only the cipher data and the specified transforms are enumerated for the decryptor, in the order necessary to obtain the octets. Consequently, because it has different semantics Transforms is in the &xenc; namespace.The schema definition is as follows:
