    I thought that might be the case. In which case, it might be better to allow
    someone to add a trusted key, supplying both encrypted and unencrypted
    versions of the data so that the TPM need not be consulted. You might want to
    mark such a key so that it can be seen when it is dumped.

    But if you're going to use a user-defined key, you really need to prefix the
    description with something suitable.
