GFpECSet

Developer Reference for Intel® Integrated Performance Primitives Cryptography

Sets up the parameters of an elliptic curve over a finite field.

Syntax

IppStatus ippsGFpECSet(const IppsGFpElement* pA, const IppsGFpElement* pB, IppsGFpECState* pEC);

ippcp.h

pA	Pointer to the coefficient `A` of the equation defining the elliptic curve.
pB	Pointer to the coefficient `B` of the equation defining the elliptic curve.
pEC	Pointer to the context of the elliptic curve.

This function assigns input values to the parameters of the elliptic curve in the IppsGFpECState context, if they are supplied.

Only the pEC parameter is required. You can omit the other parameters by setting their values to NULL or zero.

ippStsNoErr	Indicates no error. Any other value indicates an error or warning.
ippStsNullPtrErr	Indicates an error condition if pEC is NULL.
ippStsContextMatchErr	Indicates an error condition in the following cases: IppsGFpECState context parameter does not match the operation. pA or pB is not zero, and the corresponding context parameter does not match the operation.
ippStsOutOfRangeErr	Indicates an error condition if pA or pB does not belong to the finite field specified by the pGFp context.
