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(p) element (that is, the length of the DL-based cryptosystem in bits)

reBits

Bitsize of the multiplicative subgroup GF(r).

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.
