NAME
       EncryptDataFinal,  CSSM_EncryptDataFinal, CSP_EncryptDataFinal - Final‐
       ize staged encryption process (CDSA)

SYNOPSIS
       # include <cdsa/cssm.h>

       API: CSSM_RETURN CSSMAPI CSSM_EncryptDataFinal  (CSSM_CC_HANDLE	CCHan‐
       dle,  CSSM_DATA_PTR RemData) SPI: CSSM_RETURN CSSMCSPI CSP_EncryptData‐
       Final	(CSSM_CSP_HANDLE    CSPHandle,	  CSSM_CC_HANDLE     CCHandle,
       CSSM_DATA_PTR RemData)

LIBRARY
       Common Security Services Manager library (libcssm.so)

API PARAMETERS
       The  handle  that describes the context of this cryptographic operation
       used to	link  to  the  CSP-managed  information.   A  pointer  to  the
       CSSM_DATA  structure  for  the  last  encrypted block containing padded
       data, if necessary.

SPI PARAMETERS
       The handle that describes the  add-in  cryptographic  service  provider
       module  used  to perform calls to CSSM for the memory functions managed
       by CSSM.

DESCRIPTION
       This function finalizes the staged encryption process by returning  any
       remaining  cipher  text	not returned in the previous staged encryption
       call.  The cipher text is returned in a single buffer.

NOTES FOR API
       The output is returned to the caller either by filling the caller-spec‐
       ified  buffer  or by using the application's declared memory allocation
       functions to allocate buffer space. To specify a specific, preallocated
       output  buffer,	the  caller  must  provide  an	array  of  one or more
       CSSM_DATA structures, each containing a Length field value greater than
       zero and a non-NULL data pointer field value. To specify automatic out‐
       put buffer allocation by the CSP, the caller must provide an  array  of
       one  or more CSSM_DATA structures, each containing a Length field value
       equal to zero and a NULL data pointer field value. The  application  is
       always  responsible  for	 deallocating  the memory when it is no longer
       needed.

NOTES FOR SPI
       The output is returned to the caller as specified in  Buffer Management
       for Cryptographic Services.

RETURN VALUE
       A CSSM_RETURN value indicating success or specifying a particular error
       condition. The value CSSM_OK indicates success. All other values repre‐
       sent an error condition.

ERRORS
       Errors	are   described	  in   the   CDSA   technical  standard.   See
       CDSA_intro(3).	  CSSMERR_CSP_BLOCK_SIZE_MISMATCH     CSSMERR_CSP_OUT‐
       PUT_LENGTH_ERROR
