Get Size Of Temporary Buffer

Get the size for the temporary buffer that is required for the ippsXMSSVerify function (bytes).

Syntax

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

Include Files

ippcp.h

Parameters

pSize	Pointer to the signature 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

This function gets the size of the temporary buffer. 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`.
