Please forgive me if this is not the right place, however, I encountered this TLS implementation with a function that generates an ECDH key pair on an elliptic curve:

In addition to the private key and a point on the curve, the function also needs random inputs. Why and for what are the random variables required? Why isn't it just Q=d*G$Q=[d]G$?
