DESInit
DESInit
Initializes user-supplied memory as the
IppsDESSpec
context for future use (deprecated). Syntax
IppStatus ippsDESInit(const Ipp8u*
pKey
, IppsDESSpec*
pCtx
);
Include Files
ippcp.h
Parameters
- pKey
- Pointer to the DES key.
- pCtx
- Pointer to theIppsDESSpeccontext being initialized.
Description
This algorithm is considered weak due to known attacks on it. The functionality remains in the library, but the implementation will no longer be optimized and no security patches will be applied. A more secure alternative is available: AES.
This function initializes the memory pointed by
pCtx
as IppsDESSpec
context. In addition, the function uses the key 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 any of the specified pointers isNULL.
