Initialize LMS Key Pair State
Syntax
IppStatus ippsLMSInitKeyPair (const IppsLMSAlgoType OIDAlgo,
Ipp32s extraBufSize,
IppsLMSPrivateKeyState* pPrvKey,
IppsLMSPublicKeyState* pPubKey);

ippcp.h
Parameters
OIDAlgo |
LMS Algorithm ID. It defines a set of LMS parameters. See Supported LMS Algorithms for more information. |
extraBufSize |
Size of extra buffer allocated as part of the private key state. It is useful for storing tree nodes that are near the root. The larger this value, the less execution time for signature generation. |
pPrvKey |
Pointer to the IppsLMSPrivateKeyState context. Size is greater or equal to the value returned by the ippsLMSPrivateKeyStateGetSize function. |
pPubKey |
Pointer to the IppsLMSPublicKeyState context. Size is greater or equal to the value returned by the ippsLMSPublicKeyStateGetSize function. |
Description
This function initializes states for private and public keys.
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 |
pPrvKey or pPubKey is a NULL pointer. |
ippStsLengthErr |
extraBufSize < 0. |
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. |
