Qualified sign an existing PDF file

[Elio Mota]

hi there,

I am new using syncfusion and i need help.

I need to use syncfusion to signing an existing pdf file. (i already see code examples!)

- i need it to work on c# Framework 3.5 or max on 4.6, is it possible?

- do you have a dll just for pdf? 

can you direct me to the right direction?

thanks in advance
