BlowfishPack, BlowfishUnpack

Packs/unpacks the IppsBlowfishSpec context into/from a user-defined buffer.

Syntax

IppStatus ippsBlowfishPack (const IppsBlowfishSpec* pCtx, Ipp8u* pBuffer);

IppStatus ippsBlowfishUnpack (const Ipp8u* pBuffer, IppsBlowfishSpec* pCtx);

Parameters

pCtx	Pointer to the IppsBlowfishSpec context.
pBuffer	Pointer to the user-defined buffer.

Description

This functions are declared in the ippcp.h file. The BlowfishPack function transforms the *pCtx context to a position-independent form and stores it in the *pBuffer buffer. The BlowfishUnpack function performs the inverse operation, that is, transforms the contents of the *pBuffer buffer into a normal IppsBlowfishSpec context. The BlowfishPack and BlowfishUnpack functions enable replacing the position-dependent IppsBlowfishSpec context in the memory.

Call the BlowfishGetSize function prior to BlowfishPack/BlowfishUnpack 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 is NULL.
