How can I digitally sign a PDF document?


Hi,
I am trying to figure out how to digitally sign a PDF document. I need to be able to create a document or spreadsheet, print it to PDF and then digitally sign the PDF document.

In windows I was able to do this with Adobe Acrobat. I could create the document, print to Adobe PDF and then open the document with Adobe and place a digital signature on the document.

The digital signature I was able to create with Adobe and it basically had my name, an expiration date, the date of the signature and a few other bits of information. It was a visible block of information placed on the PDF document so you could see it when you printed it.

Is there any way to do this in Linux? If not I may need to try to get Adobe Acrobat working with WINE.

Thanks in advanced,
SinGuy

Well, I'm not sure if there's a way for FREE, but there may be some things that do work under Linux, that'll do this. See if these help:

It's Java based, and it mentions Linux, but I've no idea if it's any good, works, or what...your mileage may vary. You can also use GPG to 'sign' a document. It'll put a certificate on it that's verifiable, but not what you get with Adobe, though....

And I'm sure you've already gone through OpenOffice, and explored the security tab under the "export as PDF" option.....

Now I'm wondering if there is a way for me to install Adobe Acrobat Standard 8 on my FC11 laptop. This is the full version not just the Reader. WINE does not support it. Is there any other way other than possibly installing a virtual machine and running Windows to get this program running?

Yep...as you said, running Windows in a VM is the only way to do it. Aside from the Reader, you're out of luck with most of Adobe's products. It does stink out loud, though....
