OMG that looks very much like the nightmare solutions that Poland implemented back in ~2005 as part of the EU eSig Directive.
It was completely unusable with like ~10 incompatible solutions from different vendors, each of them with requirements like "Windows XP SP2 with ASP.NET 3.5" and still crashing frequently.
EU directive left quite a lot of choice in terms of implementation, and that was used in the worst possible way back then...
