Method Detail

createDigestedDataStream

public byte[] createDigestedDataStream(byte[] message,
                                       int mode)
                                throws iaik.cms.CMSException,
                                       java.io.IOException

Creates a CMS DigestedData object.

Parameters:: message - the message to be digested, as byte representation; mode - IMPLICIT (include message) or EXPLICIT (do not include message)
Returns:: the DER encoding of the DigestedData object just created
Throws:: iaik.cms.CMSException - if the DigestedData object cannot be created; java.io.IOException - if an I/O error occurs

getDigestedDataStream

public byte[] getDigestedDataStream(byte[] digestedData,
                                    byte[] message)

                                    java.io.IOException

Parses a CMS DigestedData object and verifies the hash.

Parameters:: digestedData - DigestedData object as DER encoded byte array; message - the the message which was transmitted out-of-band
Returns:: the inherent message as byte array
Throws:: iaik.cms.CMSException - if any signature does not verify; java.io.IOException - if an I/O error occurs

createDigestedData

public iaik.asn1.ASN1Object createDigestedData(byte[] message,
                                               int mode)
