Hello Thorsten,

thanks for your fast reply :)

I forgot to say that I only consider ODF version 1.2^^ However, I knew 
this webpage. As I understand it, here are defined the algorithms that 
need to be supported at least (or rather according to the 
specification). What I'm looking for is a documentation or specification 
of how ODF is implemented in application software (in this case 
LibreOffice) in terms of encryption and decryption. Analyzing the 
programming code is complicated and would take quite a bit of time^^

I also found this:

https://ringlord.com/dl/Decrypting%20ODF%20Files.pdf

This is a good explanation, but unfortunately no officially confirmed 
source (I need that for my master thesis).

Ok thanks, I will keep this in my mind ;)
