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.
