-----------------------------------------------------------
It happens with any protected open document format (odt,ods,odp) (given as
stream not file) parsed by open document parser.
Infering from the decompiled code the open document parser has two way of
parsing document it seems either as ZipFile (In case the stream is
TikaInputStream and returns true for hasFile() method) or as ZipStream
otherwise.
The problem occurs in the ZipStream logic - when we give tika the InputStream
and not the path

> Project: Tika
> Issue Type: Bug
> Components: parser
> Affects Versions: 3.2.1
> Environment: Ubuntu 24.04.2 LTS x86_64
> Reporter: Manish S N
> Priority: Minor
> Labels: encryption, odf, open-document-format, protected, zip
> Attachments: protected.odt

> When passing inputstream of protected odf format file to tika we get a
> ZipException instead of a EncryptedDocumentException.
> This works well and correctly throws EncryptedDocumentException if you create
> TikaInputStream with Path or call TikaInputStream.getPath() as it will write
> to a temporary file in memory.
> But when working with InputStreams we get the following zip exception:
