Syntax#

IppStatus ippsXMSSPublicKeyStateGetSize (Ipp32s* pSize, IppsXMSSAlgo OIDAlgo);

IppStatus ippsXMSSPrivateKeyStateGetSize (Ipp32s* pSize, IppsXMSSAlgo OIDAlgo);

IppStatus ippsXMSSSignatureStateGetSize (Ipp32s* pSize, IppsXMSSAlgo OIDAlgo);

Include Files#

ippcp.h

Parameters#

pSize

Pointer to the state size.

OIDAlgo

XMSS Algorithm ID. It defines a set of XMSS parameters. See Supported XMSS Algorithms for more information.

Description#

ippsXMSSPublicKeyStateGetSize gets the size of the public key state that is defined by OIDAlgo.

ippsXMSSPrivateKeyStateGetSize gets the size of the private key state.

ippsXMSSSignatureStateGetSize gets the size of the signature state.

The result is stored to *pSize.
