1. Can’t you use keytool.exe to do this also?  It comes with the Notes 8 client

2. Well the reason for using PKCS#12 is that it contains private and public key. A certificate os just a certified public key. The reason I need the private key is for signing Java extensions.

4. I have Jdk1.6.0_24  now and can not use this KeystoreUtil. I get the ClassNotFoundException. Is there some incompatability in the version of jdk I am using? How can I make this utilty work?

   I am trying to Convert our certificate from PKCS#12 to Java Keystore format, so that we can sign 3rd party plugins.

   All your assistance is much appreciated.

5. Seems like the jar-file with the KeystoreUtil isn’t on the classpath. How are you invoking the program?

6. Indeed KeystoreUtil.jar is not found because it is not under my Java install folders. I downloaded/installed the jdk from this http://www.oracle.com/technetwork/java/javase/downloads/index.html oracle site.

   Do I need to download extra jar files as well? If so, where do I get these from? I notice, there is tools.jar in the "lib" folder and not sure what would be in this jar file.

8. I got it work after running this command jar -cvf KeystoreUtil.jar KeystoreUtil.class to create the KeystoreUtil.jar file.

   I am new to java and went away to find out how to create my jar file from the class file you had provided.
