I tagged 0.6.0 release as I reached an important milestone i.e., now
Box<dyn TpmObject> is doable meaning that tpm2_protocol is capable of
dynamically interpreting on-wire TPM2 protocol traffic. It's proved by
this test:
https://github.com/puavo-org/tpm2_library/blob/main/tpm2sh/tests/dynamic.rs
This matters because it is the essence of being able to work as part
of driver, TPM emulator/chip or resource manager implementation.
This has required really going through the whole implementation and
deocoupling step by step the implementation from lifetime parameters
and finally implementing 'core::any::Any'.
Lot's of bugs have also been fixed in the protocol crate, tpm2sh crypto
module etc. The TCG specification coverage has increased and it is only
few dozen command/responses away from full TCG TPM 2.0 spec version 184
coverage. Given the efficient macro system this is coverage shortage
is mostly due lack of being more interested on more important matters.
My demo for this version is the cool pretty printer in tpm2sh :-)
