Parameters
pMsg |
Pointer to the message that have been signed. |
msgLen |
Message length. |
pSign |
Pointer to the IppsLMSSignatureState context for each verification operation. Size is greater or equal to the value returned by the ippsLMSSignatureStateGetSize function. |
pIsSignValid |
Pointer to the verification result. |
pKey |
Pointer to the IppsLMSPublicKeyState context for each verification operation. Size is greater or equal to the value returned by the ippsLMSPublicKeyStateGetSize function. |
pBuffer |
Pointer to the temporary buffer. Size is greater or equal to the value returned by the ippsLMSBufferGetSize function. |
Description
This function verifies the signature generated using LMS.
pIsSignValid is an output parameter. If *pIsSignValid == 1 then the LMS signature is valid. If *pIsSignValid == 0 then the LMS signature is invalid.
Important
This is a Preview Feature. You need to enable the IPPCP_PREVIEW_LMS macro to use the feature.Return Values
ippStsNoErr |
Indicates no error. All single operations executed without errors. Any other value indicates an error or warning. |
ippStsNullPtrErr |
Any of the input parameters is a NULL pointer. |
ippStsBadArgErr |
wrong LMS or LM-OTS parameters inside pSign and pKey or q is incorrect. |
ippStsContextMatchErr |
pSign or pKey contexts are invalid. |
ippStsLengthErr |
msgLen < 1 or msgLen < IPP_MAX_32S - (22 + n), where n is the LM-OTS parameter. |
