Method Details

isSignatureCovered

public boolean isSignatureCovered(org.apache.pdfbox.pdmodel.interactive.digitalsignature.PDSignature signature)

This test checks that the signature and the data signed by this signature is covered by this document timestamp. This test does NOT verify that this signature belongs to this document. The only thing that is tested is that the byte range of this signature falls within the byte range of the document timestamp.

Other functions must be used to assure that the signature in question belongs to the same document as the document timestamp.

Parameters:

signature - PDF signature

Returns:

true if this signature falls within the byte range of the signed data of this document timestamp.
