PortableSigner is a Java application to sign normal PDF files with a digital signature (X.509). You can verify your signature by opening the PDF file in a standard Adobe Reader without any plugins.

Signatureblock has now three available positions: extra page at the end of the document, on the first page, or on the last page. You can specify the position on the options page (only in metric for the moment). Java 1.7 is now used. GTK+ layout is now used under Linux. Due to massive problems with the automatic installation of the "Java Unrestricted Security Policy" under Windows, the option has been dropped in the installer. You must copy the files to the correct directory manually
