DESGetSize

Gets the size of the
IppsDESSpec
context (deprecated).

Syntax

IppStatus ippsDESGetSize(int*
pSize
);
Include Files
ippcp.h
Parameters
pSize
Pointer to the
IppsDESSpec
context size value.
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 gets the
IppsDESSpec
context size in bytes and stores it in
*pSize
.
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
.
