NAME

CSSM_SignDataFinal, CSP_SignDataFinal — Complete the final stage of the sign data (CDSA)

SYNOPSIS

# include <cssm.h>
API:
CSSM_RETURN CSSMAPI CSSM_SignDataFinal
(CSSM_CC_HANDLE CCHandle,
CSSM_DATA_PTR Signature)
SPI:
CSSM_RETURN CSSMCSPI CSP_SignDataFinal
(CSSM_CSP_HANDLE CSPHandle,
CSSM_CC_HANDLE CCHandle,
CSSM_DATA_PTR Signature)

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.

Signature (output)
  

A pointer to the CSSM_DATA structure for the signature.

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.

DESCRIPTION

This function completes the final stage of the sign data function.

NOTES ON API

The output is returned to the caller either by filling the caller-specified 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 output 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 ON SPI

The output is returned to the caller as specifed 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 represent an error condition.

ERRORS

Errors are described in the CDSA Technical Standard.
