> AES_128_GCM does not work for attachments
> -----------------------------------------
> 
> Key: WSS-566
> URL: https://issues.apache.org/jira/browse/WSS-566
> Project: WSS4J
> Issue Type: Bug
> Components: WSS4J Core
> Affects Versions: 2.0.1
> Reporter: Namrata Jaiswal
> Assignee: Colm O hEigeartaigh
> Priority: Critical
> Fix For: 2.0.7, 2.1.5
> 
> Attachments: graycol.gif, graycol.gif, graycol.gif, graycol.gif

> 
> When trying use stax APIs to encrypt and decrypt attachments using AES_GCM_128, it \
> breaks with error saying  Caused by: java.lang.IllegalStateException: Cipher not \
> initialized at javax.crypto.Cipher.d(Unknown Source)
> at javax.crypto.Cipher.doFinal(Unknown Source)
> at javax.crypto.CipherInputStream.close(Unknown Source)
> Please note that same code works for AES_128 with attachments.
> Also, I looked into the code stax code, found that \
> org.apache.xml.security.stax.impl.processor.input.AbstractDecryptInputProcessor.processEvent(InputProcessorChain, \
> boolean) has  final int ivLength = \
> JCEAlgorithmMapper.getIVLengthFromURI(algorithmURI) / 8;  Not sure if ivLength used \
> for GCM could be the problem?
