Initializes user-supplied memory as IppsDAARijndael192State context for future use.
IppStatus ippsRijndael192Init(const Ipp8u* pKey, IppsDAARijndaelKeyLength keyLen, IppsRijndael192State* pCtx);
pKey |
Pointer to the Rijndael192 key. |
keyLen |
Key byte stream length in bytes defined by the IppsRijndaelKeyLength enumerator. |
pCtx |
Pointer to the IppsDAARijndael192State context being initialized. |
This function is declared in the ippcp.h file. The function initializes the memory pointed by pCtx as the IppsDAARijndael192State 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. |
