.SH "DESCRIPTION"
.PP
\fBTspi_Context_GetKeyByUUID\fR searches the Persistent Storage database for a registered key using the
given UUID. It then creates a key object initialized to the found data and
returns a handle to the key object.

.SH "PARAMETERS"
.PP
.SS hContext
The \fIhContext\fR parameter is the handle of the context object.
.SS persistentStorageType
The \fIpersistentStorageType\fR parameter indicates the persistent
storage the key is registered in.
.SS uuidData
The \fIuuidData\fR parameter is the UUID by which the key is registered in
persistent storage.
.SS phKey
The \fIphKey\fR parameter receives the handle of the key object representing
the key.

.SH "RETURN CODES"
.PP
\fBTspi_Context_GetKeyByUUID\fR returns TSS_SUCCESS on success,
otherwise one of the following values is returned:
.TP
.SM TSS_E_INVALID_HANDLE
\fIhContext\fR is an invalid handle.

.TP
.SM TSS_E_PS_KEY_NOTFOUND
The key cannot be found in the persistent storage database.

.TP
.SM TSS_E_INTERNAL_ERROR
An internal SW error has been detected.

.TP
.SM TSS_E_BAD_PARAMETER
One or more parameters is bad.

.SH "CONFORMING TO"
