GFpECKeyExchangeSM2_GetSize¶
Gets the size of the SM2 Key Exchange Elliptic Curve context.
Syntax¶
IppStatus ippsGFpECKeyExchangeSM2_GetSize(const IppsGFpECState* pEC, int* pSize)
Include Files¶
ippcp.h
Parameters¶
pEC |
Pointer to the elliptic curve context. |
pSize |
Pointer to the size, in bytes, of the IppsGFpECKeyExchangeSM2State context. |
Description¶
The function computes the size of the buffer, in bytes, for the IppsGFpECKeyExchangeSM2State context to be used later.
The pEC parameter represents a properly initialized elliptic curve using the SM2 Key Exchange scheme.
Return Values¶
