So what would be happy response times?

Based on what I can see from core vendors for FPGAs, I think that we
should be able to do a RSA-2048 operation in something like 300 ms, or
even faster than that. A guesstimate for RSA-4096 is around a second.
There seems to be few cores that supports keys beyond 2048 bits.


Thanks for helping out defining use case requirements.
