ENCRYPT protocol UnrecoverableKeyException: Given final block not properly padded --------------------------------------------------------------------------------- Key: JGRP-1257 URL: https://jira.jboss.org/browse/JGRP-1257 Project: JGroups Issue Type: Bug Affects Versions: 2.7, 2.8, 2.11 Environment: Windows XP SP3, Java 1.6 Reporter: Andres Garcia Garcia Assignee: Bela Ban Fix For: 2.12 Attachments: JGroups-example-2.zip, JGroups-example.zip Recently I updated my jgroups version from 2.4.x to 2.11. Suddenly my applications thrown this exception. org.jgroups.ChannelException: unable to setup the protocol stack: Given final block not properly padded at org.jgroups.JChannel.init(JChannel.java:1574) at org.jgroups.JChannel.<init>(JChannel.java:257) at org.jgroups.JChannel.<init>(JChannel.java:240) at org.jgroups.demos.Draw.<init>(Draw.java:52) at org.jgroups.demos.Draw.main(Draw.java:141) Caused by: java.security.UnrecoverableKeyException: Given final block not properly padded at com.sun.crypto.provider.SunJCE_z.a(DashoA13*..) at com.sun.crypto.provider.JceKeyStore.engineGetKey(DashoA13*..) at java.security.KeyStore.getKey(Unknown Source) at org.jgroups.protocols.ENCRYPT.initConfiguredKey(ENCRYPT.java:269) at org.jgroups.protocols.ENCRYPT.init(ENCRYPT.java:231) at org.jgroups.stack.ProtocolStack.initProtocolStack(ProtocolStack.java:641) at org.jgroups.stack.ProtocolStack.setup(ProtocolStack.java:468) at org.jgroups.JChannel.init(JChannel.java:1570) ... 4 more The ENCRYPT protocol config is <ENCRYPT sym_init="448" sym_algorithm="Blowfish" encrypt_entire_message="true" key_store_name="cloudencrypt.keystore" store_password="password" alias="test"/> I tested the same code with different versions. 2.6.15 GA is the last working version, and every version I tested from 2.7 GA to 2.11 GA throw the same exception. I made a little use case with it. Maybe I am missing something?
