1) In my patch I was using org.apache.pdfbox.exceptions class. In the final
revision I can't find that class. where does they are?
2) I have just change that exception for testing. I have tested
org.apache.pdfbox.examples.signature.CreateSignature and everything works well.
3) At the moment I'm testing
org.apache.pdfbox.examples.signature.CreateTSASignature (That is document level
signature using TSA response). That was working well, but now something wrong
happens.
Adobe reader tells me that:
"There are errors in the formatting or information contained in the signature
(Support information: SigDict/Contants illegal data)l" I will see that's wrong
happens.

> When we was signing document, we was using time from our time. For more
> security we can use Time Stamp server.
> "Trusted timestamping is the process of securely keeping track of the
> creation and modification time of a document. Security here means that no one
> — not even the owner of the document — should be able to change it once it
> has been recorded provided that the timestamper's integrity is never
> compromised."(wiki)
