Subject: [PATCH 1/2] DHKE should return canonical EC point

The shared secret used on the diffie-hellman protocol will be an
elliptic curve point. It will be up to the user whether he wants to use
the 32-byte scalar representation of the Y coordinate or perform
operations with the shared secret.

The motivation is to not enforce the user to reconstruct the point in
case he need to perform ECC operations.

+# 0.3.4
+### Fix
+- Fix `dhke` to return an elliptic curve point instead of scalar.
+
 # 0.3.3
 ### Fix
 - Fix `GENERATOR_NUMS` value and add tests to check it's correct.
