Tim Allison commented on TIKA-1761:
-----------------------------------

It looks like we have no support for encryption for doc or ppt...unless I'm mistaken.

What's the pw for the docs you sent?

> I've debugged Tika library and found that it fails UserEditAtom.encryptSessionPersistIdRef property. This property is empty in files created with Office 2007 and no-empty with Office 2013.
> I've defragmented PPT files as described in https://social.msdn.microsoft.com/Forums/en-US/e33189a5-0b00-44b7-b084-f2757e9b7536/powerpoint-binary-file-format-decryption?forum=os_binaryfile
> Is this bug of Tika or POI library? 
> Should be it supported per Apache POI [encryption support|https://poi.apache.org/encryption.html]?
