MS-Office>2007 and Libreoffice protected files

[carliedu]

I'm curious to know, why openssl still cannot decrypt CDFV2 Encrypted docx, xlsx, etc. files, created by MS-Office>2007 and Libreoffice 7.

I can think of two reasons:

1. nobody was written the code for the project
2. there doesn't seem a lot of utility in having it. I.e. it doesn't prevent one from needing MS-Office or Libreoffice to use the files (since the are "their" format) and if you've got them, they are perfectly able to decrypt the files.
