XMSS

Functions such as XMSS signature verification and special functions like getters and setters that are required to call algorithms have been implemented.

Example

#define IPPCP_PREVIEW_XMSS
#include "ippcp.h"

...

IppsXMSSAlgo alg_id = IppsXMSSAlgo::XMSS_SHA2_16_256;
status = ippsXMSSBufferGetSize(&buffSize, sizeof(msg), alg_id);

status = ippsXMSSPublicKeyStateGetSize(&ippcpPubKeySize, alg_id);

status = ippsXMSSSignatureStateGetSize(&sigBuffSize, alg_id);

status = ippsXMSSSetPublicKeyState(alg_id, pRoot, pSeed, pPubKey);

status = ippsXMSSSetSignatureState(alg_id, idx, r, pOTSSign, pAuthPath, pSignature);

int is_valid=0;
status = ippsXMSSVerify(msg, sizeof(msg), pSignature, &is_valid, pPubKey, pScratchBuffer);
