Subject [jira] [Commented] (PDFBOX-2469) javax.crypto.BadPaddingException in PDFBox 1.8.8-SNAPSHOT
Date Mon, 17 Nov 2014 10:24:34 GMT

    [ https://issues.apache.org/jira/browse/PDFBOX-2469?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=14214493#comment-14214493
] 

Andreas Lehmkühler commented on PDFBOX-2469:
--------------------------------------------

I read a lot about the BadPaddingException and learned the the usage of the CipherInputStream
should be avoided. I've replaced at least one peice of code to avoid the particular stream
and now the BadPaddingException is gone. There is still one part left which doesn't seem to
be critical but maybe it's a good idea to change that part as well
