Digital signature and PDF format

Recently the Adobe PDF format has been recognized  valid as format for digital signature by CNIPA.

Nicola Bugini, Adobe Senior Application Engineer, published a great article on Acrobat User Group Italy blog where he explains how to apply a digital signature in a PDF document using Adobe Acrobat 7 Professional.

The article is in italian language but you can translate it into english :)
