Packs/unpacks the IppsRSAState context into/from a user-defined buffer.
IppStatus ippsRSAPack (const IppsRSAState* pCtx, Ipp8u* pBuffer);
IppStatus ippsRSAUnpack (Ipp8u* pBuffer, const IppsRSAState* pCtx);
pCtx |
Pointer to the IppsRSAState context. |
pBuffer |
Pointer to the user-defined buffer. |
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.
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. |
