Nikos Mavrogiannopoulos commented:


The status of the code in `tmp-tpm2` branch is that it incorporates the tpm2 code and will load (non-legacy) files with the TSS header from `gnutls_privkey_import_x509_raw` (and other high level functions which use it).

There is an incomplete test of this functionality which uses tpm2-tools, but I'm stuck with being able to convert from the form `tpm2-tools` outputs, to the PEM form and the TSS header.

There are few options at this point:
 - One option is to extend tpm2-tools to output the PEM form. I've opened https://github.com/tpm2-software/tpm2-tools/issues/1599
 - Give up transparent loading and have a tpm2 specific routine (looks like a usability nightmare)
 - Give up on direct usage of tpm2 keys and rely on https://github.com/tpm2-software/tpm2-pkcs11
