NAME
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.
None specific to this call.
