(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

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.
