RSAPack, RSAUnpack

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

Syntax

IppStatus ippsRSAPack (const IppsRSAState* pCtx, Ipp8u* pBuffer);

IppStatus ippsRSAUnpack (Ipp8u* pBuffer, const IppsRSAState* pCtx);

Parameters

pCtx

Pointer to the IppsRSAState context.

pBuffer

Pointer to the user-defined buffer.

Description

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

Call the RSAGetSize function prior to RSAPack/RSAUnpack 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.
