Also tpm2-protocol is dependencyless, no crazy corporate TPM2 shenanigans and daemons involved etc., meaning that overall tpm2sh is quite self-contained and good fit but 8 KSLOC not really to be imported (the size comes from built-in TPM2 emulator, policy expression language and advanced import functionality that directly converts PKCS#8 to TPM2 Key ASN.1 DEr/PEM all super useful for all sorts of testing purposes). > > [1] https://github.com/puavo-org/tpm2sh > [2] > https://git.kernel.org/pub/scm/linux/kernel/git/jarkko/tpm2-protocol.git/about/ > > BR, Jarkko > >
