TPMs and secure elements


I’m building some tools that center around secure device identity and authentication, and I’m curious what the community is using to secure private keys on devices.

There are some challenges in getting the Infineon TPM running with the Raspberry Pi 4, and I’d love some confirmation that I’m building a prototype that represents what people are doing in the real world.

Thanks in advance!

I already raised once discussion about support for TPM module. I think that it is very dangerous to store all data on SD card, that could be plugged out and anyone could read anything. Zymbit looks like solution for storage of private keys and for entire SD card encryption (
