[jira] [Updated] (PDFBOX-3984) Add validation data of signer to document

     [ https://issues.apache.org/jira/browse/PDFBOX-3984?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel ]

Alexis Suter updated PDFBOX-3984:
---------------------------------
    Attachment: SignatureValidation_v0.1.java.patch

I have kept the new files in its own package to keep them distinguished. Maybe a helper-package would be nice, because there are multiple helpers around now.
Also I have created two new Exceptions: CertificateProccessingException to indicate an error with certificate Structure. And RevokedCertificateException, because the existing Exception (CertificateRevokedException) needs too much informations.
usage: exec:java -X -Dexec.mainClass="org.apache.pdfbox.examples.signature.validation.AddValidationInformation" -Dexec.args="${infile}"

> To support Long Term Validation of a signature, we need to add a Valdiation-Dictionary to the document. Inside there is most importantly an OCSP-Response of the signers. (can be multiple).
> As Defined in [PAdES 4|https://en.wikipedia.org/wiki/PAdES] the following elements will be added to a document: A DSS (Document Security Store) linked to the VRI(s) of the signature(s)
> At first I will provide an example.
