feBitSize
, int *
pSize
);

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.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 isNULL.
- ippStsSizeErr
- Indicates an error condition if the value of the parameterfeBitSizeis less than 2.
