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]?
