GFPXECSet

Sets up parameters of the elliptic curve in the IppsGFPXECState context.

Syntax

IppStatus ippsGFPXECSet(const IppsGFPXElement *pA, const IppsGFPXElement *pB, const IppsGFPXElement *pX, const IppsGFPXElement *pY, const Ipp32u *pOrder, Ipp32u orderLen, Ipp32u cofactor, IppsGFPXECState *pEC);

Parameters

pA	Pointer to the `A` parameter of the elliptic curve.
pB	Pointer to the `B` parameter of the elliptic curve.
pX, pY	Pointers to the `x` and `y` coordinates of the base point of the elliptic curve.
pOrder	Pointer to the array storing the order of the base point.
orderLen	Length of the array storing the order of the base point.
cofactor	The value of the cofactor.
pEC	Pointer to the context of the elliptic curve.

Description

This function is declared in the ippcp.h file. The function assigns values to the parameters of the elliptic curve in the IppsGFPXECState context.

Return Values

ippStsNoErr	Indicates no error. Any other value indicates an error or warning.
ippStsNullPtrErr	Indicates an error condition if the pEC pointer is NULL.
ippStsContextMatchErr	Indicates an error condition if any of the context parameters does not match the operation.
