PoC using swtpm

[theMiddleBlue]

Hi,

AFAIK DBSC on chrome could also work with a software TPM, is it correct? Is there any chance of getting a guide on how to create a PoC for DBSC functionality using swtpm on Linux? Specifically, I'm looking for steps to configure swtpm and integrate it with Chrome for testing DBSC. Any resources or guidance would be greatly appreciated.

Following what I'm trying to do but doesn't seems to work. I'm just checking the presence of navigator.securesession API:

$ mkdir /tmp/mytpm1
$ swtpm socket --tpmstate dir=/tmp/mytpm1 --ctrl type=unixio,path=/tmp/mytpm1/swtpm-sock --log level=20 --tpm2

other process:

sudo socat UNIX-LISTEN:/dev/tpm0,fork UNIX-CONNECT:/tmp/mytpm1/swtpm-sock

Thank you!
