DB init without python on embedded target?

[milkylainen]

Maybe something simpler, without sqlite, written in C for the smaller target trying to use tpm2 as a pkcs11 store?

sqlite is the database to store the necessary metadata, it's as simple as a database can get - the alternative would be to implement a file based backend, which comes with another set of issues.

About python, if I'm not mistaken, you may chose to not use the tpm2_ptool and invoke pkcs11-tool directly, with some limitations however.
