NAME
CSSM_SignDataUpdate, CSP_SignDataUpdate — Continue the staged signing process input buffer data
(CDSA)
SYNOPSIS
# include <cssm.h>
API:
CSSM_RETURN CSSMAPI CSSM_SignDataUpdate
(CSSM_CC_HANDLE CCHandle,
const CSSM_DATA *DataBufs,
uint32 DataBufCount)
SPI:
CSSM_RETURN CSSMCSPI CSP_SignDataUpdate
(CSSM_CSP_HANDLE CSPHandle,
CSSM_CC_HANDLE CCHandle,
const CSSM_DATA *DataBufs,
uint32 DataBufCount) |
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. |
| DataBufs (input) | | A pointer to a vector of CSSM_DATA structures that
contain the data to be operated on. |
| DataBufCount (input) |
| | | The number of DataBufs to be signed. |
SPI PARAMETERS
| CSPHandle (input) |
| | | 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 continues the staged signing process over all
data contained in the set of input buffers. Signing is performed
using the private key specified in the context.
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.
