AESInit
Initializes user-supplied memory as IppsAESSpec context for future use.
Syntax
IppStatus ippsAESInit(const Ipp8u* pKey, int keylen, IppsAESSpec* pCtx, int ctxSize);
Include Files
ippcp.h
Parameters
pKey |
Pointer to the AES key. |
keylen |
Key byte stream length in bytes defined by the IppsRijndaelKeyLength enumerator. |
pCtx |
Pointer to the buffer being initialized as IppsAESSpec context. |
ctxSize |
Available size of the buffer being initialized. |
Description
This function initializes the memory pointed by pCtx as IppsAESSpec. The key is used 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 pCtx pointer is NULL. |
ippStsLengthErr |
Returns 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. |
