NAME

Tspi_Context_GetKeyByPublicInfo - search the persistent storage for a registered key using the provided public key information  

SYNOPSIS

#include <tss/platform.h>
#include <tss/tcpa_defines.h>
#include <tss/tcpa_typedef.h>
#include <tss/tcpa_struct.h>
#include <tss/tss_typedef.h>
#include <tss/tss_structs.h>
#include <tss/tspi.h>

TSS_RESULT Tspi_Context_GetKeyByPublicInfo(TSS_HCONTEXT     hContext,      TSS_FLAG  persistentStorageType,
                                           TSS_ALGORITHM_ID algID,         UINT32    ulPublicInfoLength,
                                           BYTE*            rgbPublicInfo, TSS_HKEY* phKey);

 

DESCRIPTION

TSS_Context_GetKeyByPublicInfo searches the persistent storage for a registered key using the provided public key information and creates a key object initalized according to the found data. On successful completion of the method a handle to the created new key object is returned.  

PARAMETERS

 

hContext

The handle of the context object.

 

persistentStorageType

Flag indicating the persistent storage the key is registered in.

 

algId

This parameter indicates the algorithm of the requested key.

 

ulPublicInfoLength

The length of the public key info provided at the parameter rgbPublicInfo.

 

rgbPublicInfo

The public key info is provided to identify the key to be look for at the persistent storage. In case algID equals to TSS_ALG_RSA this prameter contains the modulus of the public RSA key.

 

hKey

Recieves the handle of the key object representing the key. In case the key hasn't been found, this value will be NULL.  

RETURN CODES

Tspi_Context_GetKeyByPublicInfo returns TSS_SUCCESS on success, otherwise one of the following values are returned:

TSS_E_INVALID_HANDLE - hContext is an invalid handle.
TSS_E_INTERNAL_ERROR - An error occurred internal to the TSS.
 

CONFORMING TO

Tspi_Context_GetKeyByPublicInfo conforms to the Trusted Computing Group Software Specification version 1.1 Golden
