Parameters¶
pGFp |
Pointer to the IppsGFpState context of the underlying finite field. |
pEC |
Pointer to the cryptosystem context based on a standard elliptic curve |
Description¶
Each of these functions initializes the context of the elliptic curve cryptosystem based on a specific standard elliptic curve. For a list of these curves, see table Standard Elliptic Curves.
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. |
ippStsContextMatchErr |
Indicates an error condition if the IppsGFpECState context parameter does not match the operation. |
ippStsBadArgErr |
Indicates an error condition if the IppsGFpECState context parameterdoes not specify the finite field over which the givenstandard elliptic curve is defined. |
