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 the
IppsDESSpec
context 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 is
NULL
.
