webPDF is able to attach a digital certificate to your PDF document and to digitally sign the document in this way. By a digital signature the authenticity of your PDF document can be confirmed. Thus the file is protected from any changes or manipulations.
Using webPDF.portal you can digitally sign your document during the PDF conversion or just upload an existing PDF file to sign it. With webPDF.jclient you can convert and sign files on your own computer. The latest demo version is available for download here.
The webPDF software package contains the webPDF.jclient and your own webPDF.portal for the use in your corporate network. More information is available here.
