Hello, I'd like to highlight the command tcti's inclusion into the TSS: - https://github.com/tpm2-software/tpm2-tss/pull/1734 What's really cool, if you have tpm2_send on master post PR 2094: - https://github.com/tpm2-software/tpm2-tools/pull/2094 You can use it to run commands on remote machine. For instance, you can Run a tpm command over an SSH tunnel on a remote machine to get the quote. There will be no endianness issues in anything and no worries of how to transmit the data. Another great perk, is that if your device node has a too old version of tpm2-tools, you can just issue a partial update to tpm2_send, or provide some other command suitable. For most devices, something that can read and write a file might be useful, not really sure offhand what that would look like in entirety. Example invocation: tpm2_getrandom -T "cmd:ssh localhost tpm2_send" --hex 4 Thanks, Bill
