Hi Ilshat,

great job during last week.

Regarding the signature benchmarks it is clear that DSA is the preferable
option. However, the plot does not allow to appreciate the exact result in
seconds for DSA. Can you just post the exact numbers? We need to check if
DSA's is enough for signing and verifying a stream of chunks.

Best,

Juan
