org.bouncycastle.tsp.cms.CMSTimeStampedDataGenerator

public class CMSTimeStampedDataGenerator
extends CMSTimeStampedGenerator

Builder for an RFC 5544 TimeStampedData object. Given the initial RFC 3161 time stamp token (computed over the message imprint of the document, and the MetaData when it is hash-protected) plus the optional content set via the inherited CMSTimeStampedGenerator.setDataUri(URI)/CMSTimeStampedGenerator.setMetaData(boolean, String, String) methods, it produces a CMSTimeStampedData whose evidence chain holds that one token.

Method Details

generate

public CMSTimeStampedData generate(TimeStampToken timeStamp)
                            throws CMSException

Generate a TimeStampedData with no encapsulated content (e.g. when the document is referenced via a dataUri).

Parameters:

timeStamp - the initial time stamp token.

Returns:

the generated CMSTimeStampedData.

Throws:

CMSException - if the structure cannot be built.

generate

public CMSTimeStampedData generate(TimeStampToken timeStamp,
 byte[] content)
                            throws CMSException

Generate a TimeStampedData encapsulating the passed in content.

Parameters:

timeStamp - the initial time stamp token.

content - the document content to encapsulate.

Returns:

the generated CMSTimeStampedData.

Throws:

CMSException - if the structure cannot be built.

generate

public CMSTimeStampedData generate(TimeStampToken timeStamp,
 InputStream content)
                            throws CMSException

Generate a TimeStampedData encapsulating the content drained from the passed in stream.

Parameters:

timeStamp - the initial time stamp token.

content - a stream over the document content to encapsulate, or null for none.

Returns:

the generated CMSTimeStampedData.

Throws:

CMSException - if the content cannot be read or the structure cannot be built.
