Get Size Of Temporary Buffer

Get Size Of Temporary Buffer#

Get the size for the temporary buffer (bytes).

Syntax#

IppStatus ippsXMSSBufferGetSize       (Ipp32s* pSize, Ipp32s maxMessageLength, IppsXMSSAlgo OIDAlgo);

IppStatus ippsXMSSKeyGenBufferGetSize (Ipp32s* pSize, IppsXMSSAlgo OIDAlgo);

IppStatus ippsXMSSSignBufferGetSize   (Ipp32s* pSize, Ipp32s maxMessageLength, IppsXMSSAlgo OIDAlgo);

IppStatus ippsXMSSVerifyBufferGetSize (Ipp32s* pSize, Ipp32s maxMessageLength, IppsXMSSAlgo OIDAlgo);

Include Files#

ippcp.h

Parameters#

pSize

Pointer to the state size.

maxMessageLength

Maximum length of the message that needs to be verified. It can be the maximum of all messages’ length that can potentially be passed to the verification function.

OIDAlgo

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

Description#

Note

ippsXMSSBufferGetSize is deprecated. Please refer to Deprecated Functions section for the recommendations for transition.

ippsXMSSKeyGenBufferGetSize gets the size of the temporary buffer required for ippsXMSSKeyGen.

ippsXMSSSignBufferGetSize gets the size of the temporary buffer required for ippsXMSSSign.

ippsXMSSVerifyBufferGetSize gets the size of the temporary buffer required for ippsXMSSVerify.

The result is stored to *pSize.

Note

Important

You need to enable the IPPCP_PREVIEW_XMSS macro to use the feature. For more information, see Preview Features.

Return Values#

ippStsNoErr

Indicates no error. All single operations executed without errors. Any other value indicates an error or warning.

ippStsNullPtrErr

pSize is a NULL pointer.

ippStsLengthErr

maxMessageLength < 1 or maxMessageLength < IPP_MAX_32S - (10 + len) * n, where n, len are WOTS+ parameters.

ippStsBadArgErr

OIDAlgo < 1 or OIDAlgo > the maximum value for IppsXMSSAlgo.
