1 - Yes, iText fully supports PAdES Part 2.

2 - PadES does not, currently, support parts 3 or 4 of PAdES - but it would be 
wonderful if you (or someone else) would develop it and contribute it back.

Subject: [iText-questions] PAdES

Hi,

I want to write a program using IText, which will sign PDF documents conforming 
to PDF Advanced Electronic Signature Profiles (PAdES). Unfortunatelly I cannot 
find much info about this issue on the web and IText book is not ready yet - 
http://itextpdf.com/book/index.php. I have some questions:

1. Is TimestampOCSP example on IText page 
(http://itextpdf.com/examples/index.php?page=example&id=225) compatible with 
"ETSI TS 102 778-2 Part 2: PAdES Basic - Profile based on ISO 32000-1"? If not, 
why?
2. Is there a way in IText to implement "ETSI TS 102 778-4 (Part 4: PAdES Long 
Term - PAdES-LTV Profile)" - A.1 Document Security Store and A.2 Document 
Time-stamp? I found one example on this forum: 
http://comments.gmane.org/gmane.comp.java.lib.itext.general/50888 but nobody 
was able to say if the code is correct.

Thank you very much.
Juraj
