NAME
CSSM_EncryptDataInit, CSP_EncryptDataInit — Initialize the staged encrypt funciton (CDSA)
SYNOPSIS
# include <cssm.h>
API:
CSSM_RETURN CSSMAPI CSSM_EncryptDataInit
(CSSM_CC_HANDLE CCHandle)
SPI:
CSSM_RETURN CSSMCSPI CSP_EncryptDataInit
(CSSM_CSP_HANDLE CSPHandle,
CSSM_CC_HANDLE CCHandle,
const CSSM_CONTEXT *Context,
CSSM_PRIVILEGE Privilege) |
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 calls to CSSM for the memory
functions managed by CSSM. |
| Context (input) | | Pointer to CSSM_CONTEXT structure that describes
the attributes with this context. |
| Privilege (input) |
| | | The export privilege to be applied during the cryptographic
operation. This parameter is forwarded to the CSP after CSSM verifies
the caller and service provider privilege set includes the specified
PRIVILEGE. |
DESCRIPTION
This function initializes the staged encrypt function. There
may be algorithm-specific and token-specific rules restricting the
lengths of data following data update calls making use of these
parameters.
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.
