Does the emulator show the unseal failing? I.e., is the TPM return code
not success? If so, I can help. If not, you need a trousers expert.

After some further debugging, without much to show for it, I've found
that I had an issue where the tpm emulator was complaining about
Tspi_LoadKeyByUUID, which appears to have been due to the key requiring
authorisation, as such, GetKeyByUUID and LoadKey has to be used instead,
while this has silenced the only error the tpm emulators is giving me,
it still leads to tspi_data_unseal producing the return code 1. Making
the matter more confusing is that, despite the key apparently not
loading properly, tspi_data_seal was and is still working fine. Any
support here would be greatly appreciated.
