CRYPT_ECC_DHE_KeyMake Function

C

int CRYPT_ECC_DHE_KeyMake(
    CRYPT_ECC_CTX* ecc, 
    CRYPT_RNG_CTX* rng, 
    int keySz
);

Description

This function creates a new ECC key.

Preconditions

The context must have been initialized with a call to CRYPT_ECC_Initialize. The random number generator context must have been initialized with a call to CRYPT_RNG_Initialize.

Parameters

Parameters	Description
ecc	Pointer to context which saves state between calls.
rng	Pointer to the context for the random number generator.
keySz	The size of the key desired.

Returns

BAD_FUNC_ARG - An invalid pointer was passed to the function.
MEMORY_E - Could not create the memory buffer for the key.
0 - An invalid pointer was not passed to the function.

Remarks

None.

Example

CRYPT_ECC_CTX userA; 
int           ret;
byte          sharedA[100];
unsigned int  aSz = (unsigned int)sizeof(sharedA);
unsigned int  usedA = 0;

ret = CRYPT_ECC_Initialize(&userA);
ret = CRYPT_ECC_DHE_KeyMake(&userA, &mcRng, 32);
