Hmm. Interesting suggestion. Maybe I failed to understand the purpose
of the domain field. From my understanding it is used only for key generation,
isn't it? Does it have any other usecases?

I thought about gost r 34.10 signatures as if they are 'just another format' of
ecdsa signatures. Thus I added a (flag gost) to data/signature generation.
IIUC, there is no any significant difference between ECDSA and GOST

What do you think?

With best wishes
