ECCPSetPoint
Sets coordinates of a point on the elliptic curve defined over GF(p).
Syntax
IppStatus ippsECCPSetPoint(const IppsBigNumState* pX, const IppsBigNumState* pY, IppsECCPPointState* pPoint, IppsECCPState* pECC);
Include Files
ippcp.h
Parameters
pX |
Pointer to the x-coordinate of the point on the elliptic curve. |
pY |
Pointer to the y-coordinate of the point on the elliptic curve. |
pPoint |
Pointer to the context of the elliptic curve point. |
pECC |
Pointer to the context of the elliptic cryptosystem. |
Description
The function sets the coordinates of a point on the elliptic curve defined over a prime finite field GF(p).
The context of the point on the elliptic curve must be already created by functions: ECCPPointGetSize and ECCPPointInit. The elliptic curve domain parameters must be hitherto defined by one of the functions: ECCPSet or ECCPSetStd.
Return Values
ippStsNoErr |
Indicates no error. Any other value indicates an error or warning. |
ippStsNullPtrErr |
Indicates an error condition if any of the specified pointers is NULL. |
ippStsContextMatchErr |
Indicates an error condition if one of the contexts pointed by pX, pY, pPoint, or pECC is not valid. |
