-----------------------------------
Summary: AES_GCM_128 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
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?
