Macros
#define	XSECURE_ECC_TRNG_DF_LENGTH (2U)
	Default length of xilsecure ecc true random number generator. More...

#define	XSECURE_ECC_TRNG_RANDOM_NUM_GEN_LEN (60U)
	Length of xilsecure ecc true random number generator. More...

Functions
EcdsaCrvInfo *	XSecure_EllipticGetCrvData (XSecure_EllipticCrvTyp CrvTyp)
	This function gets the curve related information. More...

int	XSecure_EllipticPrvtKeyGenerate (XSecure_EllipticCrvTyp CrvType, XSecure_ElliptcPrivateKeyGen *PrivateKey)
	This function generates 48-byte key for P-384 curve using TRNG. More...

int	XSecure_EllipticGenerateEphemeralKey (XSecure_EllipticCrvTyp CrvType, u32 EphemeralKeyAddr)
	This function generates 48-byte ephemeral key for P-384 curve using TRNG. More...

int	XSecure_EllipticGenEphemeralNSign (XSecure_EllipticCrvTyp CrvType, const u8 Hash, u32 HashLen, u8 PrvtKey, u8 *Signature)
	This function generates the signature on provided hash using ecc. More...

int	XSecure_EcdhGetSecret (XSecure_EllipticCrvTyp CrvType, u64 PrvtKeyAddr, u64 PubKeyAddr, u64 SharedSecretAddr)
	This is a wrapper function which calls the IPCores API to perform ECDH and generate shared secret. More...
