Description

PPT documents created (or saved) as Powerpoint 97-2003 format and protected with password against modification using Office 2013 fail during extracting text.
But it works fine Powerpoint 97-2003 format using Office 2007

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?
