ECCPInit¶
Initializes the context for the elliptic curve cryptosystem over GF(p).
Syntax¶
IppStatus ippsECCPInit(int feBitSize, IppsECCPState* pECC);
Include Files¶
ippcp.h
Parameters¶
feBitSize |
Size (in bits) of the underlying prime number. |
pECC |
Pointer to the cryptosystem context. |
Description¶
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.
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. |
ippStsLengthErr |
Indicates an error condition if the value of thefeBitsize parameter is less than 2 or greater than1024. |
