NAME

CSSM_CSP_CreatePassThroughContext — Create a custom cryptographic context (CDSA)

SYNOPSIS

# include <cssm.h>
CSSM_RETURN CSSMAPI CSSM_CSP_CreatePassThroughContext
(CSSM_CSP_HANDLE CSPHandle,
const CSSM_KEY *Key,
CSSM_CC_HANDLE *NewContextHandle)

LIBRARY

Common Security Services Manager library (cdsa$incssm300_shr.exe)

PARAMETERS

CSPHandle (input)
  

The handle that describes the add-in Cryptographic Service Provider module used to perform this function. If a NULL handle is specified, CSSM returns an error.

Key (input) 

The key to be used for the context. The caller passes a pointer to a CSSM_KEY structure containing the key.

NewContextHandle (output)
  

Cryptographic context handle.

DESCRIPTION

This function creates a custom cryptographic context, given a handle of a CSP and a pointer to a custom input data structure. The cryptographic context handle is returned. The cryptographic context handle can be used to call the CSSM pass-through function for the CSP.

NOTES

A CSP can create its own set of custom functions. The context information can be passed through its own data structure. The CSSM_CSP_PassThrough() function should be used with the function ID to call the desired custom function.

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.
