AESSetKey¶
Resets the AES secret key in the initialized IppsAESSpec context.
Syntax¶
IppStatus ippsAESSetKey(const Ipp8u* pKey, int keylen, IppsAESSpec* pCtx);
Include Files¶
ippcp.h
Parameters¶
pKey |
Pointer to the AES key. |
keylen |
Length of the secret key. |
pCtx |
Pointer to the initialized IppsAESSpec context. |
Description¶
This function resets the AES secret key in the initialized IppsAESSpec context with the user-supplied secret key.
Note
If the pKey pointer is NULL, the function resets the context with the zero key, which can help you to clean up the actual secret before releasing the context.
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. |
