How to get permissions of the file?

[EvgeniiG]

Hello!

I have a file(s) with some permissions (like in the picture).

How I can read these permission(s) for prepending users to upload this file to the server?

I used pdfservices library for Java.

PS: The file with the properties above is already signed.

Ask the makers of the library. You aren't using Adobe products for this.

Thanks for the answer but what does this mean?

Sorry, my mistake. I didn't realise that this is the name of an Adobe product. I think they changed the name.  Anyway, it isn't the Acrobat SDK so this is the wrong forum. But there is an active forum here -- https://community.adobe.com/t5/document-services-apis/ct-p/ct-Document-Cloud-SDK?page=1&sort=latest_...
