NAME

Tspi_Context_GetRegisteredKeysByUUID - get an array of TSS_KM_KEYINFO
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/tss_structs.h>
#include <tss/tspi.h>

TSS_RESULT Tspi_Context_GetRegisteredKeysByUUID(TSS_HCONTEXT hContext, TSS_FLAG persistentStorageType,
TSS_UUID* pUuidData, UINT32* pulKeyHierarchySize,
TSS_KM_KEYINFO** ppKeyHierarchy);

DESCRIPTION

TSS_Context_GetRegisteredKeysByUUID gets an array of TSS_KM_KEYINFO
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_KEYINFO structure contins data
reflecting the whole key hierarchy starting with root key. If a
certain key is UUID is provided, the returned array of TSS_KM_KEYINFO
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_GetRegisteredKeysByUUID 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_GetRegisteredKeysByUUID conforms to the Trusted
Computing Group Software Specification version 1.1 Golden
