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