AES_GCMProcessIV¶
Processes an initial vector of a given length according to the GCM specification.
Syntax¶
IppStatus ippsAES_GCMProcessIV(const Ipp8u* pIV, int ivLen, IppsAES_GCMState* pState);
Include Files¶
ippcp.h
Parameters¶
pIV |
Pointer to the initialization vector. |
ivLen |
Length of the initialization vector *pIV (in bytes). |
pState |
Pointer to the IppsAES_GCMState context. |
Description¶
The function processes ivLen bytes of the initial vector *pIV as specified in [NIST SP 800-38D].
Return Values¶
ippStsNoErr |
Indicates no error. Any other value indicates an error or warning. |
ippStsNullPtrErr |
Indicates an error condition if any of the specified pointers is NULL. |
ippStsContextMatchErr |
Indicates an error condition if the context parameter does not match the operation. |
ippStsLengthErr |
Indicates an error condition if the length of the initialization vector is zero. |
ippStsBadArgErr |
Indicates an error condition if the pState parameter value is not GcmInit or GcmIVProcessing. This means that the function call sequence is illegal. |
