Creates the shared secret value according to [IEEE1363, ANS X9.63]:
Checks input-parameter pointers and EC Domain in public and private keys.
Derives the partner public key and calls the EcWrstDhDeriveSharedSecret function, which performs EC SVDP operations.
- The term "User" refers to any party that calculates a shared secret value using this primitive. The term "Partner" refers to any other party of shared secret value calculation. Partner's public key shall be validated before using in this primitive.
- CRYS_OK on success.
A non-zero value on failure as defined crys_ecpki_error.h.
