public class CMSSignedDataOutputStream
A CMSSignedDataOutputStream
writes its output in the form of a CMS signed-data
structure, signing the data in the process.
Specifically, the effect of using this class is as if the following process took place:
signed-data
.except that the actual process is done in one pass, eliminating the necessity to accumulate all of the input data before writing any output.
In the case where a <ocde>CMSConnector is provided instead of a CMSOutputStream
, only the exposed content i.e. the Content field of the ContentInfo structure minus the explicit [0] tag is written to the underlying output stream.
IMPORTANT: This class generates large CMS signed-data Objects more efficiently (Java VM memory usage) than the CMSSignedDataContentInfo
class.
