[jira] [Commented] (PDFBOX-2776) support "Long Term Validation" signature extensions (LTV)

    [ https://issues.apache.org/jira/browse/PDFBOX-2776?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=15454408#comment-15454408 ] 

Ralf Hauser commented on PDFBOX-2776:
-------------------------------------

Sure, an example for LTV like the one for TSA or even without the code that obtains the ocsp-response (just take the BouncyCastle class for it and assume it is externally provided) would make me happy!

> in recent acrobat readers, every signature is commented w.r.t. "LTV"
> ETSI TS 102 778-4 V1.1.2 (2009-12) Technical Specification
> referenced as part 4 in
> http://en.wikipedia.org/wiki/PAdES 
> It would be great if pdf signatures created with PDFBox would assist in creatign those.
> Target test setup: 
> 1) input of an unsigned PDF-1.5 document
> 2) signature with
> a) local key pair
> b) hsm
> c) remote signature service (e.g. via soap)
> 3) add ocsp response for LTV (crls typically are larger)
> ==> Result: signed pdf where acrobat reader claims it to be "LTV enabled"
