sign pdf with trusted certificate
- 
					
					
					
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 ...

You can find the steps on how to create a working certificate here

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?

Yes.
We aren't Certifying Authority so we aren't providing certificates.
This should be a list of authorities providing the signing certificates
