public class CMSEnvelopedDataInputStream
A CMSEnvelopedDataInputStream
is used to read enveloped-data
CMS objects.
A CMSEnvelopedDataInputStream
is essentially a input stream filter that unwraps the CMS enveloped-data
structure from the data read in.
IMPORTANT: This class processes large CMS enveloped-data Objects more efficiently (Java VM memory usage) than the CMSEnvelopedDataContentInfo
class.
