------------------------------
I checked out the latest JGroups from CVS,
cvs -z3 -d:pserver:anonymous@javagroups.cvs.sourceforge.net:/cvsroot/javagroups co -P
JGroups
and re-ran the NotificationBusDemo (with Encrption enabled). Now whenever I start an
instance of NotificationBusDemo class I get "ChannelNotConnectedException" error
message. I don't get this error with the same test on CR1 code base. Attached is the
updated NotificationBusDemo class (note I've modified the memberJoined method to send
out notification as that's required by my application).
Here is the output on the console,

ENCRYPT protocol throwing IllegalBlockSizeException
---------------------------------------------------
Key: JGRP-538
URL: http://jira.jboss.com/jira/browse/JGRP-538
Project: JGroups
Issue Type: Bug
Affects Versions: 2.5
Environment: Windows, Linux
Reporter: vivek v
Assigned To: Bela Ban
Fix For: 2.5
I use NotificationBus channel and in the member joined method I call,
bus.sendNotification(Node) - passing a custom Node object. Upon this I get the following
error on the newly joined member,
javax.crypto.IllegalBlockSizeException: Input length must be multiple of 8 when
decrypting with padded cipher
at com.sun.crypto.provider.SunJCE_f.b(DashoA13*..)
at com.sun.crypto.provider.SunJCE_f.b(DashoA13*..)
at com.sun.crypto.provider.DESCipher.engineDoFinal(DashoA13*..)

at org.jgroups.protocols.ENCRYPT.handleUpMessage(ENCRYPT.java:672)
at org.jgroups.protocols.ENCRYPT.up(ENCRYPT.java:533)
I could reproduce the same problem using NotificationBusDemo.java in JGroups 2.5 CR1.
Here is what I did,
1) Generate a keystore using JGroups' KeyStoreGenerator (I also tried with JDK
1.6's keytool to generate secret key)
2) Add the following line in the protocol stack of NotificationBusDemo.java in the
main(),
"ENCRYPT(key_store_name=jgroups.keystore;store_password=storePassed;alias=mykey):"
+
3) Add the following line in the memberJoined(..) method of NotificationBusDemo.java
bus.sendNotification("Member Joined");
4) Run 2 instances of NotificationBusDemo.java
5) You'll get the following error message,
> 3828 [WARN] ENCRYPT.up(): - exception occurred decrypting message
javax.crypto.BadPaddingException: Given final block not properly padded
at com.sun.crypto.provider.SunJCE_h.b(DashoA12275)
at com.sun.crypto.provider.SunJCE_h.b(DashoA12275)
I am running this on Windows using JGroups 2.5 CR1. The original thread for this issue
is at,
