Hello,
I'd like to add some support of Overwatch into CascLib.
Because basically each build has its own key+IV generation, I would take the CMF sources from TACTLib, convert them into C++ and then include them into CascLib. It can be automated due to good similarity between C++ and C#.
AFAIK it should be OK with the MIT license used by TACTLib. I just want to ask nicely :-)
