Initializes user-supplied memory as IppsDAARijndael256State context for future use.
IppStatus ippsDAARijndael256Init(const Ipp8u* pKey, IppsDAARijndaelKeyLength keyLen, IppsRijndael256State* pCtx);
pKey |
Pointer to the Rijndael256 key. |
keyLen |
Key byte stream length in bytes defined by the IppsRijndaelKeyLength enumerator. |
pCtx |
Pointer to the IppsDAARijndael256State being initialized. |
This function is declared in the ippcp.h file. The function initializes the memory pointed by pCtx as the IppsDAARijndael256State context. In addition, the function uses the key to provide all necessary key material for both encryption and decryption operations.
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. |
ippStsLengthErr |
Indicates an error condition if keyLen is not equal to IppsRijndaelKey128, IppsRijndaelKey192, or IppsRijndaelKey256. |
