encrypted document appears empty
I am trying to open an encrypted document in Ubuntu 21.04 with frontends that use poppler (eg Okular, etc) and in all of them
- the frontend does not ask for a password,
- the document is empty.
Unfortunately I cannot share the document, but I would like to do my best providing debugging information. In particular, is there anything I can do with poppler in the command line that would reproduce this or provide debugging info?
I would do it for the current version (libpoppler107 (= 21.02.0-1)) and also compile master from the git repo.
(Sorry if this information is in the docs or the wiki, I would not find it).
Some output from
R = 4 P = -4 User password = REDACTED Supplied password is owner password Supplied password is user password extract for accessibility: allowed extract for any purpose: allowed print low resolution: allowed print high resolution: allowed modify document assembly: allowed modify forms: allowed modify annotations: allowed modify other: allowed modify anything: allowed stream encryption method: AESv2 string encryption method: AESv2 file encryption method: AESv2
Firefox (88.0.1+build1-0ubuntu0.21.04.2) opens the PDF just fine, after asking for a password. `
