Confirm in 7.4 and in 5.2.7.2 (In reply to Roman Kuznetsov from comment #4) > Confirm in 7.4 and in 5.2.7.2 Not exactly. Before 6.2, all versions behave differently: they ask for password repeatedly several times, after which (if not cancelled) the file is opened in Writer (showing junk). The related change is commit ce560ee99ebf97fa44aecedd5110b29913cf77a5 Author Tomaž Vajngerl <tomaz.vajngerl@collabora.co.uk> Date Wed Jul 04 22:23:44 2018 +0200 oox: Agile encryption and data integrity verification Note that regardless, this is not a regression of any kind; it could never be opened. This is AES 256-bit encryption. Lo has multiple bugs for opening AES PDF. If XLSX is saved in MSO as XLS, it's with a weak encryption so it opens in LO.

Opening an AES-256 encrypted PDF will leverage xpdf and of necessity be a different solution from opening an AES-256 encrypted XLSX. Despite the superficial similarity of the problem statements, there is not a common root cause between the two so I don't expect there to be any significant overlap in the resolution. I'm seeing the exact same problem on 7.4.7 as shipped by Ubuntu 22.10.1 |
