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

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

Aeham Abushwashi updated TIKA-2300:
-----------------------------------
    Attachment: encrypted_file.zip

The attached file can be used to repro. It is protected with a password, "password123", using ZipCrypto

>             Project: Tika
>          Issue Type: Bug

> 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
