Developer Reference for Intel® Integrated Performance Primitives Cryptography
Initializes the context for the elliptic curve cryptosystem over GF(p).
IppStatus ippsECCPInit(int feBitSize, IppsECCPState* pECC);
ippcp.h
feBitSize |
Size (in bits) of the underlying prime number. |
pECC |
Pointer to the cryptosystem context. |
The function initializes the context of the elliptic curve cryptosystem over the 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.
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. |
ippStsLengthErr |
Indicates an error condition if the value of the feBitsize parameter is less than 2 or greater than 1024. |
