NAME    [Toc]    [Back]

       DecryptDataP - Decrypt data with privilege (CDSA)

SYNOPSIS    [Toc]    [Back]

       # include <cdsa/cssm.h>

       CSSM_RETURN   CSSMAPI   CSSM_DecryptDataP  (CSSM_CC_HANDLE
       CCHandle, const CSSM_DATA *CipherBufs,  uint32  CipherBufCount,
   CSSM_DATA_PTR  ClearBufs,  uint32  ClearBufCount,
       uint32 *bytesDecrypted, CSSM_DATA_PTR RemData, CSSM_PRIVILEGE
 Privilege)

LIBRARY    [Toc]    [Back]

       Common Security Services Manager library (libcssm.so)

PARAMETERS    [Toc]    [Back]

       The privilege to be applied during the cryptographic operation.


       See CSSM_DecryptData() for other parameters.

DESCRIPTION    [Toc]    [Back]

       This function is similar to  CSSM_DecryptData().  It  also
       accepts  a USEE tag as a privilege request parameter. CSSM
       checks that either its privilege set or the  application's
       privilege  set (if the application is signed) includes the
       tag. If the tag is found and the service  provider  privilege
  set  indicates that it is supported, the tag is forwarded
 to the service provider.

RETURN VALUE    [Toc]    [Back]

       A CSSM_RETURN value indicating  success  or  specifying  a
       particular  error  condition.  The value CSSM_OK indicates
       success. All other values represent an error condition.

ERRORS    [Toc]    [Back]

       Errors are described in the CDSA technical standard.   See
       CDSA_intro(3).     CSSMERR_CSP_BLOCK_SIZE_MISMATCH    CSSMERR_CSP_OUTPUT_LENGTH_ERROR
