Get Size Of Temporary Buffer

Get Size Of Temporary Buffer#

Get the size for the temporary buffer (bytes).

Syntax#

IppStatus ippsLMSBufferGetSize (Ipp32s* pSize,
                                Ipp32s maxMessageLength,
                                const IppsLMSAlgoType OIDAlgo);

IppStatus ippsLMSKeyGenBufferGetSize (Ipp32s* pSize, const IppsLMSAlgoType OIDAlgo);

IppStatus ippsLMSSignBufferGetSize (Ipp32s* pSize,
                                    Ipp32s maxMessageLength,
                                    const IppsLMSAlgoType OIDAlgo);

IppStatus ippsLMSVerifyBufferGetSize (Ipp32s* pSize,
                                      Ipp32s maxMessageLength,
                                      const IppsLMSAlgoType OIDAlgo);

ippcp.h

Parameters#

pSize

Pointer to the temporary buffer size.

maxMessageLength

Maximum length of the message. It can be the maximum length of all messages that can potentially be passed to the corresponding function, e.g. ippsLMSSign, ippsLMSKeyGen or ippsLMSVerify.

OIDAlgo

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

Description#

Note

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

ippsLMSKeyGenBufferGetSize gets the size of the temporary buffer required for ippsLMSKeyGen.

ippsLMSSignBufferGetSize gets the size of the temporary buffer required for ippsLMSSign.

ippsLMSVerifyBufferGetSize gets the size of the temporary buffer required for ippsLMSVerify.

The result is stored to *pSize.

Note

Important

You need to enable the IPPCP_PREVIEW_LMS 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 - (22 + n), where n is the LM-OTS parameter.

ippStsBadArgErr

OIDAlgo.lmotsOIDAlgo < the minimum value for IppsLMOTSAlgo, OIDAlgo.lmotsOIDAlgo > the maximum value for IppsLMOTSAlgo, OIDAlgo.prmLmsAlg < the minimum value for IppsLMSAlgo or OIDAlgo.prmLmsAlg > the maximum value for IppsLMSAlgo.
