TSS_RESULT Tspi_Key_WrapKey(TSS_HKEY hKey, TSS_HKEY hWrappingKey,
TSS_HPCRS hPcrComposite);
DESCRIPTION
TSS_Key_WrapKey wraps the private key hKey using the public key ad‐
dressed by hWrappingKey. If hPcrComposite is not set to NULL (0), the
created key blob is bound to its PCR values. The key object addressed
by hKey must contain the key information needed for the creation. On
successful return from this call, hKey can be loaded into a TPM. hKey
must have been created as a migratable key and should have its usage
and migrations secrets set using Tspi_Policy_SetSecret(3). Also, hKey
should have had its private key set to either RSA private component, p
or q.
PARAMETERS
hKey
The handle of the key object that is wrapped.
hWrappingKey
The handle to the key used to wrap the newly created key.
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.
RETURN CODESTspi_Key_WrapKey returns TSS_SUCCESS on success, otherwise one of the
following values are returned:
TSS_E_INVALID_HANDLE - Either hKey, hWrappingKey or hPcrComposite are
invalid handles.
TSS_E_INTERNAL_ERROR - An error occurred internal to the TSS.
