Set PDF->Document Properties->Security->Signing With iTextSharp

[Polymorpher]

Does anyone have any idea how to take a PDF and set this property using iTextSharp or any other free open source tool? Basically the idea is that we have a program generating PDF's and we want to be able to have someone in the office sign the document and then pass it down the line to the next person. Everything I have found has pointed to buying one tool or another, but we would really like to be able to do this without buying any tools. Thanks in advance for any help!

I know its a bit late, but here is a very nice article i found about signing of PDFs using iTextsharp and hence stopping others from tempering it. I hope its helpful for you.
