[jira] [Resolved] (TIKA-2300) Can't tell if a zip file is encrypted

["Tim Allison (JIRA)" <ji...@apache.org>]

     [ https://issues.apache.org/jira/browse/TIKA-2300?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel ]

Tim Allison resolved TIKA-2300.
-------------------------------
       Resolution: Fixed
    Fix Version/s: 1.15
                   2.0

[~aeham.abushwashi] I added a stacktrace to the parent's metadata object for encrypted files, or for any stream that can't be read.

Going forward, it will be helpful to figure out how to determine a) encryption (for non-zip) files or b) other reasons that a stream might not be readable.

For now, the embedded exception is an encryption exception for your test stream and a general TikaException for any other reason that a package stream can't be read.

Thank you for the issue and the patch!

> When Tika processes a zip file that is protected with a password, it will return the list of file names within the zip but no indication (as an exception or in metadata) that the file is encrypted. 
> From stepping through the code, I can see that the information needed to determine whether the archive is encrypted is available inside ZipArchiveEntry#getGeneralPurposeBit#usesEncryption, but needs to be relayed back to PackageParser somehow
