[jboss-jira] [JBoss JIRA] Resolved: (JGRP-538) ENCRYPT protocol throwing IllegalBlockSizeException

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 Attachments: NotificationBusDemo.java 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 javax.crypto.Cipher.doFinal(DashoA13*..) at org.jgroups.protocols.ENCRYPT._decrypt(ENCRYPT.java:838) at org.jgroups.protocols.ENCRYPT.decryptMessage(ENCRYPT.java:831) 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.
