AES_CMACInit
Initializes user-supplied memory as IppsAES_CMACState context for future use.
Syntax
IppStatus ippsAES_CMACInit(const Ipp8u* pKey, int keyLen, IppsAES_CMACState* pState, int ctxSize);
Include Files
ippcp.h
Parameters
pKey |
Pointer to the AES key. |
keyLen |
Key bytestream length (in bytes) defined by the IppsAESKeyLength enumerator. |
pState |
Pointer to the memory buffer being initialized as IppsAES_CMACState context. |
ctxSize |
Available size of the buffer. |
Description
This function initializes the memory at the address of pState as the IppsAES_CMACState context. In addition, the function uses the key to provide all necessary key material for both encryption and decryption operations.
Return Values
ippStsNoErr |
Indicates no error. Any other value indicates an error or warning. |
ippStsNullPtrErr |
Indicates an error condition if the pState pointer is NULL. |
ippStsLengthErr |
Indicates an error condition if keyLen is not equal to 16, 24, or 32. |
ippStsMemAllocErr |
Indicates an error condition if the allocated memory is insufficient for the operation. |
