EncryptDataInit

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.
