Functions
WOLFSSL_LOCAL int	wc_GenerateSeed (OS_Seed *os, byte *seed, word32 sz)
WOLFSSL_API int	wc_InitNetRandom (const char *, wnr_hmac_key, int)
	Init global Whitewood netRandom context.
WOLFSSL_API int	wc_FreeNetRandom (void)
	Free global Whitewood netRandom context.
WOLFSSL_ABI WOLFSSL_API WC_RNG *	wc_rng_new (byte *, word32, void *)
WOLFSSL_ABI WOLFSSL_API void	wc_rng_free (WC_RNG *)
WOLFSSL_API int	wc_InitRng (WC_RNG *)
	Gets the seed (from OS) and key cipher for rng. rng->drbg (deterministic random bit generator) allocated (should be deallocated with wc_FreeRng). This is a blocking operation.
WOLFSSL_API int	wc_InitRng_ex (WC_RNG *rng, void *heap, int devId)
WOLFSSL_API int	wc_InitRngNonce (WC_RNG *rng, byte *nonce, word32 nonceSz)
WOLFSSL_API int	wc_InitRngNonce_ex (WC_RNG *rng, byte *nonce, word32 nonceSz, void *heap, int devId)
WOLFSSL_ABI WOLFSSL_API int	wc_RNG_GenerateBlock (WC_RNG *, byte *, word32 sz)
	Copies a sz bytes of pseudorandom data to output. Will reseed rng if needed (blocking).
WOLFSSL_API int	wc_RNG_GenerateByte (WC_RNG *, byte *)
	Calls wc_RNG_GenerateBlock to copy a byte of pseudorandom data to b. Will reseed rng if needed.
WOLFSSL_API int	wc_FreeRng (WC_RNG *)
	Should be called when RNG no longer needed in order to securely free drgb. Zeros and XFREEs rng-drbg.
WOLFSSL_LOCAL int	wc_RNG_DRBG_Reseed (WC_RNG *rng, const byte *entropy, word32 entropySz)
WOLFSSL_API int	wc_RNG_TestSeed (const byte *seed, word32 seedSz)
WOLFSSL_API int	wc_RNG_HealthTest (int reseed, const byte *entropyA, word32 entropyASz, const byte *entropyB, word32 entropyBSz, byte *output, word32 outputSz)
	Creates and tests functionality of drbg.
WOLFSSL_API int	wc_RNG_HealthTest_ex (int reseed, const byte *nonce, word32 nonceSz, const byte *entropyA, word32 entropyASz, const byte *entropyB, word32 entropyBSz, byte *output, word32 outputSz, void *heap, int devId)
