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,
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.....
