Dependency graph of tpm2sh showing the crates that realize the tool. It's a bit different take than TSS2 :-)

tpm2sh 0.15.0 compiles the policy commands to the DER payload.

Crypto has been migrated to OpenSSL for sake of allowing to be (or delegating the policy of being) FIPS compatible, and making crypto patchable.

Refined the interface of offloaded objects:

1. Objects resident/loaded in TPM: tpm:
2. Offloaded objects: vtpm:

Thus, I removed also "key" and "session" subcommands and introduced "virtual" subcommand.

known bug which might be confusing but "tpm2sh certificate" does work as proven by this screenshot. it should still accept nv-index without "0x" prefix.

Finally TPM2_Import procedure for ECC or RSA primary parent fully working :-) Getting RSA-OAEP and ECDH import dance has required ridiculous amounts of times to get right but finally :-) And when it is done, it is done.

Pitäs tähän www.mindtrek.org/speaker/jark... kuva. En ota itsestäni normaalisti valokuvia, ja tuli kyllä aika kuumottavia kuvia kun koitin tähtäillä selfietä. Tää tuorein kuva minkä löysin puhelimesta ei oikein myöskään oo ehkä sopivinta matskua :-D
