Parameters
- peBits
- Bitsize of the GF(p) element (that is, the length of the DL-based cryptosystem in bits)
- reBits
- Bitsize of the multiplicative subgroup GF(r).
- pSize
- Pointer to theIppsDLPStatecontext 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 isNULL.
- ippStsSizeErr
- Indicates an error condition ifpeBits≤reBits.
