--------------------------------------
tballison merged PR #1684:
URL: https://github.com/apache/tika/pull/1684
> Figure out what to do with epubs with encrypted non-core content
> ----------------------------------------------------------------
>
> Key: TIKA-4219
> URL: https://issues.apache.org/jira/browse/TIKA-4219
> Project: Tika
> Issue Type: Task
> Reporter: Tim Allison
> Priority: Major
>
> On TIKA-4218, we noticed several epubs that were now being identified as
> encrypted, which is good. We did this work on TIKA-4176.
> On the other hand, we found several epubs that were now identified as
> encrypted but which had content before we were doing the encryption detection.
> The issue in at least one file that I reviewed is that non-core content is
> encrypted -- the fonts. So, from a text+metadata extraction, we could still
> get all the content and then throw an Encrypted Exception or maybe flag
> something as encrypted.
> I'm not sure what the best thing to do is in this case.
> An example file is here:
