SHA224Pack, SHA224Unpack
Packs/unpacks the
IppsSHA224State
context into/from a user-defined buffer.Syntax
IppStatus ippsSHA224Pack (const IppsSHA224State*
pCtx
, Ipp8u*
pBuffer
);
IppStatus ippsSHA224Unpack (const Ipp8u*
pBuffer
, IppsSHA224State*
pCtx
);

Parameters
- pCtx
- Pointer to theIppsSHA224Statecontext.
- pBuffer
- Pointer to the user-defined buffer.
Description
The
SHA224Pack
function transforms the *pCtx
context to a position-independent form and stores it in the *pBuffer
buffer. The SHA224Unpack
function performs the inverse operation, that is, transforms the contents of the *pBuffer
buffer into a normal IppsSHA224State
context. The SHA224Pack
and SHA224Unpack
functions enable replacing the position-dependent IppsSHA224State
context in the memory. Call the
SHA224GetSize
function prior to SHA224Pack
/SHA224Unpack
to determine the size of the buffer.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.
