NAME

Tspi_Context_GetRegisteredKeysByUUID2 - get an array of
TSS_KM_KEYINFO2 structures based on the state of persistent storage.

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/tspi.h>

TSS_RESULT Tspi_Context_GetRegisteredKeysByUUID2(TSS_HCONTEXT hContext, TSS_FLAG persistentStorageType,
TSS_UUID* pUuidData, UINT32* pulKeyHierarchySize,
TSS_KM_KEYINFO2** ppKeyHierarchy);

DESCRIPTION

TSS_Context_GetRegisteredKeysByUUID2 gets an array of
TSS_KM_KEYINFO2 structures. This information reflects the state of
the registered key hierarchy. The keys stored in the persistent
storage are totallly independent from either the context provided in
the function call or the context, which was provided while processing
the key registration.

PARAMETERS

hContext
The handle of the context object.

persistentStorageType
Flag indicating the persistent storage the key is registered in.

pUuidData
The UUID the key was registered in the persistent storage (TSP or
connected TCS). If no key UUID is provided, thus KeyUUID is NULL, the
returned array of the TSS_KM_KEYINFO2 structure contains data
reflecting the whole key hierarchy starting with root key. If a
certain key is UUID is provided, the returned array of
TSS_KM_KEYINFO2 structures only contains data reflecting the path of
the key hierarchy regarding that key. The first array entry is the
key addressed by the given UUID followed by its parent key up to the
root key.

pulKeyHierarchySize
Recieves the length (number of array entries) of the ppKeyHierarchy
parameter.

ppKeyHierarchy
On successful completion of the command, this parameter points to a
buffer containing the actual key hierarchy data.

RETURN CODES

Tspi_Context_GetRegisteredKeysByUUID2 returns TSS_SUCCESS on success,
otherwise one of the following values are returned:

TSS_E_INVALID_HANDLE - hContext is an invalid handle.

TSS_E_BAD_PARAMETER

TSS_E_INTERNAL_ERROR
An error occurred internal to the TSS.

CONFORMING TO

Tspi_Context_GetRegisteredKeysByUUID2 conforms to the Trusted
Computing Group Software Specification version 1.2
