Add support for the new password encryption implemented on LibreOffice documents

Your idea.

On the incoming LibreOffice 24.08, the new password encryption will be used by default, a format that OnlyOffice doesn't support yet, which means that LibreOffice documents saved on this version can't be opened.

Here's the info:

ODF Wholesome Encryption A new mode of password-based ODF encryption has been implemented, with the following advantages:

more performant due to deriving a key only once per package more tamper-resistant with authenticated encryption (AES-GCM) better hiding of metadata to reduce information leaks higher resistance to brute forcing using memory-hard Argon2id key derivation function (Michael Stahl, allotropia) tdf#105844

LibreOffice 24.08 hasn't been officially released, but the installer can be found here.

I've only tested it on the Android app (version 8.1.2.), where you get the following message: "Conversion failed".

The password of my documents is: password.
