@chrisfenner I don't know if you are interested, but here is a rewrite of age-plugin-tpm from the legacy tpm2 API to the new tpmdirect API.

I'm not sure if this works as some form of feedback or if this helps on the API design :)

Hrm, actually I tired running this on my actual TPM instead of the swtpm stuff and it fails to do ECDHZGen. Just blocks without any response from the TPM.

Age interrupting the plugin too quickly it seems(?)

We get a stanza, and we should reply with a stanza. Previously we would
intermingle this which would probably lead to a couple of subtle bugs

This also implements multiple recipients.

definitely interested, thanks for tagging me! I have filed a feature request for go-tpm to add a UnmarshalReader/MarshalReader surface, and left a few other comments on the design of your code here. Thanks for using the new go-tpm API!!
