I'm replying off-list. I think that this might be on the list of forbidden features (one would have to pay to adobe to be able to allow signing document with TeX).

Hello,
since ConTeXt supports form fields in PDFs, I wonder whether the fields for digital signatures are available as well. If not, please consider this a feature request/wish :-)
I'm not sure about it, but I'm tempted to believe that digitally signing PDFs might be one of "forbidden" functionality that requires you to buy a licence for Acrobat. Why ? As long it is described in the ISO standard, it can be implemented in mkiv (easily is another question).
