DLPGetSize

Developer Reference for Intel® Integrated Performance Primitives Cryptography

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.
