.SH "DESCRIPTION"
.PP
\fBTSS_Key_CreateKey\fR  
calls the TPM command TPM_CreateWrapKey. If hPcrComposite is not set to NULL, the created key blob is bound to this PCR values. The key object addressed by hKey must contain the key information needed for the creation. 
.SH "PARAMETERS"
.PP
.SS hKey
The handle of the key object to create.
.PP
.SS hWrappingKey
The handle to the key used to wrap the newly created key.
.PP
.SS hPcrComposite
The handle to an object, if the value of the handle doesn't equal NULL, the newly create key will be bound ot the PCR values described with this object.

.SH "RETURN CODES"
.PP
\fBTspi_Key_CreateKey\fR returns TSS_SUCCESS on success, otherwise one of the following values are returned:
.TP
.SM TSS_E_INVALID_HANDLE - Either \fIhKey\fR, \fIhWrappingKey\fR or \fIhPcrComposite\fR are invalid parameters.
.TP
.SM TSS_E_INTERNAL_ERROR - An error occurred internal to the TSS.
