void SL_HASHCALL SL_TIGER_FinalHex( void* pContext, void* pDest, int bUpper );



    [in/out] Pointer to the context.


    [out] Pointer to the text buffer that will receive the message digest.


    [in] Uppercase flag. If bUpper is 0, the received message digest represents a lowercase string, otherwise it represents an uppercase string.


Call this function to retrieve the message digest from the context pointed by pContext. The digest is retrieved as a null-terminated hexadecimal string in the text buffer pointed by pDest. The size of the text buffer pointed by pDest must be at least SLC_TIGER_HEXDIGESTSIZE characters.

After the SL_TIGER_FinalHex function  is performed, the context is initialized for new calculations, as it would be called SL_TIGER_Init again.

    file = fopen( "c:\\test.txt", "rb" );

    if( file == NULL )
        return 1;

    /*****Initialize the context before calling Update, Final, or FinalHex****/

    SL_TIGER_Init( context );

    /*****Calculate the digest by calling Update for each block of the file***/

    SL_TIGER_FinalHex( context, digesthex, 0 );

    /*****Use the digest******************************************************/

    fclose( file );
