CRYS_RSA_KG_GenerateKeyPair generates a Pair of public and private keys on non CRT mode according to [ANS X9.31].

Note:
To be FIPS 186-4 [5.1] compliant use only the following key sizes (in bits): 1024, 2048 and 3072.
Returns:
CRYS_OK on success.
A non-zero value from crys_rsa_error.h or crys_rnd_error.h on failure.
Parameters:
[in,out]rndState_ptrPointer to the RND state structure.
[in]rndGenerateVectFuncPointer to the random vector generation function.
[in]pubExp_ptrThe pointer to the public exponent (public key).
[in]pubExpSizeInBytesThe public exponent size in bytes.
[in]keySizeThe size of the key, in bits. Supported sizes are 512, 1024, 2048, 3072 and 4096 bit.
[out]userPrivKey_ptrPointer to the private key structure.
[out]userPubKey_ptrPointer to the public key structure.
[in]keyGenData_ptrPointer to a temporary structure required for the KeyGen operation.
[in]pFipsCtxPointer to temporary buffer used in case FIPS certification if required.
