Tim Allison commented on TIKA-2300:
-----------------------------------

Thank you!  I'll take a look soon.

bq. the change made me realise the rich metadata extracted by the PackageParser for the compressed/inner files never finds its way back up to users through the metadata object. Is this by design?

Via classic Tika, y, this is what happened.  This is exactly why I integrated [~jukkaz]'s and [~gagravarr]'s RecursiveParserWrapper to maintain metadata of embedded files.  Give it a try with "-J -t" from the commandline with tika-app or try "/rmeta" if you're using tika-server.

> 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
