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
NOTE:

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.
