PortableSigner - A Commandline and GUI Tool to digital sign PDF files with X.509 certificates
Start program with Java 1.5 or greater
java -jar PortableSigner
There's a minimal installer in the package PortableSigner-Generic-x.x.xxx.zip in the directory linux/.
There's a full blown installer as PortableSigner-Installer-x.x.xxx.exe.
The following additional libraries are provided and used:
- itext (siehe auch http://itext.sourceforge.net)
- BouncyCastle (siehe auch http://www.bouncycastle.org)
- Swing-layout (siehe auch http://layout.jdesktop.org)
For the use of Bouncycastle the Java Strong export Security must be used. (Look at http://www.bouncycastle.org/documentation.html):
" 3. If you are using JDK 1.4, or later, you must use the signed jar for the provider and you must download the unrestricted policy files for the Sun JCE if you want the provider to work properly. The policy files can be found at the same place as the JDK download. Further information on this can be found in the Sun documentation on the JCE. If you have not installed the policy files you will see something like:
java.lang.SecurityException: Unsupported keysize or algorithm parameters at javax.crypto.Cipher.init(DashoA6275) "
The new JCE Policy can be found http://java.sun.com/javase/downloads/index.jsp at the end of the page: "Java Cryptography Extension (JCE) Unlimited Strength Jurisdiction Policy "
If you're upgrading your Java runtime, please reinstall the policies to apply the security policies again.

Fuer die Verwendung von Bouncycastle muss das Schema fuer Strong Export Security in der Java Runtime installiert sein (siehe auch Zitat von http://www.bouncycastle.org/documentation.html):
" 3. If you are using JDK 1.4, or later, you must use the signed jar for the provider and you must download the unrestricted policy files for the Sun JCE if you want the provider to work properly. The policy files can be found at the same place as the JDK download. Further information on this can be found in the Sun documentation on the JCE.

Die neue JCE Policy ist zu finden unter http://java.sun.com/javase/downloads/index.jsp gegen Ende der Seite als: "Java Cryptography Extension (JCE) Unlimited Strength Jurisdiction Policy "
Sollten Sie Ihre Java Runtime updaten oder neu installieren, bitte die Policy noch einmal installieren, damit die Security Policy auch dort wirkt.
