public class CMSEnvelopedDataOutputStream
A CMSEnvelopedDataOutputStream
writes its output in the form of a CMS enveloped-data
structure, enveloping the data in the process.
Specifically, the effect of using this class is as if the following process took place:
enveloped-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 enveloped-data Objects more efficiently (Java VM memory usage) than the CMSEnvelopedDataContentInfo
class.
