Would be nice if there was more lean openssl like command-line tool that would all that openssl, keyctl and tpm2-tools does in this test:

Remarks:

  • openssl: RSA key generation and PEM-to-DER conversion.
  • tpm2-tools: Hardware bound object generation and raw-to-PEM conversion.
  • keyctl operates with the Linux keyring and sets up asymmetric key with private key in TPM2.

Would be nice if with one command at least I could get a DER blob with the binding to the machine where it is run and then use keyctl. Head hurts watching that script dump. I’m surprised that I got it working at all.

#linux #kernel #tpm #tpm2 #keyctl #openssl

And all TPM2 related built-in and talking to /dev/tpm0 no compromises ;-) Otherwise it is as good as tpm2-tss-engine and similar, which are not that great for my needs.
