CRYSError_t CRYS_RSA_KG_GenerateKeyPair	(	CRYS_RND_Context_t *	rndContext_ptr ,
		uint8_t *	pubExp_ptr ,
		uint16_t	pubExpSizeInBytes ,
		uint32_t	keySize ,

		CRYS_RSAKGData_t *	keyGenData_ptr ,
		CRYS_RSAKGFipsContext_t *	pFipsCtx
	)

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 on failure.

Parameters

[in,out]	rndContext_ptr	Pointer to the RND context buffer.
[in]	pubExp_ptr	The pointer to the public exponent (public key).
[in]	pubExpSizeInBytes	The public exponent size in bytes.
[in]	keySize	The size of the key, in bits. Supported sizes are 512, 1024, 2048, 3072 and 4096 bit.
[out]	userPrivKey_ptr	Pointer to the private key structure.
[out]	userPubKey_ptr	Pointer to the public key structure.
[in]	keyGenData_ptr	Pointer to a temporary structure required for the KeyGen operation.
[in]	pFipsCtx	Pointer to temporary buffer used in case FIPS certification if required.
