Hi Tobias,
Thank you for your answer. I'm on the first stage of learning TPM but as
far as I understand the general rule the private key should not be
accessible and that was a reason that aforementioned log message drew my
attention. This wiki page I've read is the only way I can learn TPM and
strongswan cooperation or there are some more detailed explanations
somewhere how the process is going?

Best regards,
