2510 Generates DH public key.
2512 This function generates random secret exponent, and computes the public key, which is
2513 returned via parameter PublicKey and PublicKeySize. DH context is updated accordingly.

2515 PublicKeySize is set to the required buffer size to obtain the public key.
2517 If DhContext is NULL, then return FALSE.
