ECCPGetOrderBitSize
Retrieves order size of the elliptic curve base point over GF(p) in bits.
Syntax
IppStatus ippsECCPGetOrderBitSize(int* pBitSize, IppsECCPState* pECC);
Include Files
ippcp.h
Parameters
pBitSize |
Pointer to the size of the base point (in bits). |
pECC |
Pointer to the cryptosystem context. |
Description
The function retrieves the order size (in bits) of the elliptic curve base point G from the context of elliptic cryptosystem over a prime finite field GF(p) and allocates it in accordance with the pointer pBitsSize. 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 the cryptosystem contextis not valid. |
