Parameters
pMsg |
Pointer to the array of messages that have been signed. |
msgLen |
Message length. |
pSign |
Pointer to the IppsXMSSSignatureState context for each verification operation. Size is greater or equal to the value returned by the ippsXMSSSignatureStateGetSize function. |
pIsSignValid |
Pointer to the verification result. |
pKey |
Pointer to the IppsXMSSPublicKeyState context for each verification operation. Size is greater or equal to the value returned by the ippsXMSSPublicKeyStateGetSize function. |
pBuffer |
Pointer to the temporary buffer. Size is greater or equal to the value returned by the ippsXMSSBufferGetSize function. |
Description
This function verifies the signature generated using XMSS.
pIsSignValid is an output parameter. If *pIsSignValid == 1 then the XMSS signature is valid. If *pIsSignValid == 0 then the XMSS signature is not valid.
Important
This is a Preview Feature. You need to enable the IPPCP_PREVIEW_XMSS 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. |
ippStsLengthErr |
msgLen < 1 or msgLen < IPP_MAX_32S - (10 + len) * n, where n, len are WOTS+ parameters``. |
