DLPGetSize¶
Gets the size of the IppsDLPState context.
Syntax¶
IppStatus ippsDLPGetSize(int peBits, int reBits, int *pSize);
Include Files¶
ippcp.h
Parameters¶
peBits |
Bitsize of the GF( |
reBits |
Bitsize of the multiplicative subgroup GF( |
pSize |
Pointer to the IppsDLPState context size in bytes. |
Description¶
The function gets the IppsDLPState context size in bytes and stores in
*pSize. DL-based cryptosystem over GF(p) assumes that r/p-1
where both p and r are primes.
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 peBits≤ reBits. |
