NAME    [Toc]    [Back]

       SignDataInit,  CSSM_SignDataInit,  CSP_SignDataInit - Initialize
 the staged sign data (CDSA)

SYNOPSIS    [Toc]    [Back]

       # include <cdsa/cssm.h>

       API: CSSM_RETURN CSSMAPI CSSM_SignDataInit (CSSM_CC_HANDLE
       CCHandle)   SPI:   CSSM_RETURN  CSSMCSPI  CSP_SignDataInit
       (CSSM_CSP_HANDLE CSPHandle, CSSM_CC_HANDLE CCHandle, const
       CSSM_CONTEXT *Context)

LIBRARY    [Toc]    [Back]

       Common Security Services Manager library (libcssm.so)

API PARAMETERS    [Toc]    [Back]

       The  handle  that  describes  the  context of this cryptographic
 operation used to link to the CSP-managed information.

SPI PARAMETERS    [Toc]    [Back]

       The handle that describes the add-in cryptographic service
       provider module used to perform up calls to CSSM  for  the
       memory functions managed by CSSM.  Pointer to CSSM_CONTEXT
       structure that describes the attributes with this context.

DESCRIPTION    [Toc]    [Back]

       This function initializes the staged sign data function.

       For  staged  operations, a combination operation selecting
       both a digesting algorithm and a signing algorithm must be
       specified.

       The CSP can require that the cryptographic context include
       access credentials for  authentication  and  authorization
       checks when using a private key or a secret key.

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).

       None specific to this call.
