  .cubepro file format and found out that it only does a Blowfish ECB encryption of the .bfb file


This implies that you need to find a slicer that outputs .bfb tool path files (similar like G-code files) and a tool to encrypt the tool path file. The dubious CodeX tool and this alternative can do that for you.
