Thanks Jan,

but by what I read, this means installing the certificate on the client machine. If open the document on another machine, acrobat would say "the signatures are not valid".

Is that true?

Hi,

as I understand it is possibile to digital signing pdf with this framework.

Do you also help in obtaining trusted certificates? how can I obtain them and use with this tool?

Apparently if I sign the pdf with my own self created certificate I get a "signature not valid" warning from acrobat ...
