how to Sign a PDF with thawte x.509 S/MIME certificate

[Morten Gulbrandsen]

it says here:

http://www.gnupg.org/

Version 2 of GnuPG also provides support for S/MIME.

Project Aegypten developed the S/MIME functionality in GnuPG 2.

my question,

can I sign a document or a pdf file with Version 2 of GnuPG ?

 Sign a PDF

You can sign a PDF to indicate your approval. A PDF can be signed more
than once and by more than one person. When you sign a document, your
digital signature appears in the signature field. The appearance of the
signature depends on options you choose. The actual information for your
digital signature is embedded in the PDF. Only PDFs with Reader Rights
enabled can be signed.

can I also sign and encrypt ?  AES256?

Sincerely yours,

Morten Gulbrandsen
