SignDataInit

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

SYNOPSIS
  # include <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
  Common Security Services Manager library (CDSA$INCSSM300_SHR.EXE)

API PARAMETERS
  CCHandle (input)
          The handle that describes the context of this cryptographic
          operation used to link to the CSP-managed information.

SPI PARAMETERS
  CSPHandle (input)
          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.

  Context (input)
          Pointer to CSSM_CONTEXT structure that describes the
          attributes with this context.

DESCRIPTION
  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
  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
  Errors are described in the CDSA technical standard.  See CDSA.

  None specific to this call.
