ECCPGetSize¶
Gets the size of the IppsECCPState context.
Syntax¶
IppStatus ippsECCPGetSize(int feBitSize, int *pSize);
Include Files¶
ippcp.h
Parameters¶
feBitSize |
Size (in bits) of the underlying prime number. |
pSize |
Pointer to the size (in bytes) of the context. |
Description¶
The function computes the size of the context in bytes for the elliptic cryptosystem over a prime finite field GF (p).
Context is a structure IppsECCPState designed to store information about the cryptosystem status.
Note
For security reasons, the length of the underlying prime number is restricted to 1 kilobit.
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. |
ippStsSizeErr |
Indicates an error condition if the value of the parameter feBitSize is less than 2. |
