Initialize an EC Private Key using {EC,G,n,x}.
ec | the elliptic curve |
G | the base point |
n | the order of the base point |
x | the private exponent |
This Initialize() function overload initializes a private key from existing parameters.

inline |
Create an EC private key.
rng | a RandomNumberGenerator derived class |
params | the EC group parameters |
This function overload of Initialize() creates a new private key because it takes a RandomNumberGenerator() as a parameter. If you have an existing keypair, then use one of the other Initialize() overloads.
