Subject [jira] [Commented] (WSS-581) Decryption fails with cipher not initialized error when multiple attachmments are used
Date Wed, 22 Jun 2016 09:48:57 GMT

    [ https://issues.apache.org/jira/browse/WSS-581?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=15344023#comment-15344023
] 

Colm O hEigeartaigh commented on WSS-581:
-----------------------------------------

No, the EncryptedData does not need to have a KeyInfo - I just did a quick test. Could you
create a test-case to reproduce the problem that I can run as a unit test in WSS4J?

> When multiple attachments are used for decrypting using Stax Apis in WSS4j, decryption
does not work
> The decryption works fine for 1st attachment (I can see that javax.security.auth.callback.CallbackHandler#handle(javax.security.auth.callback.Callback[])
API  for both AttachmentRequestCallback and AttachmentResultCallback are invoked for first
attachment and also AttachmentResultCallback returned decrypted the data )but it breaks with
error Cipher not initialized for second attachment. For 2nd attachment, AttachmentRequestCallback
goes fine where we set everything but handle call for AttachmentResultCallback breaks with
error  Cipher not initialized (before invoking password callbacks) when we try to read decrypted
data.
> 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)
