Zymkey as TPM

Can Zymkey be used as TPM for PI?

Any documentation?

Zymkey is a hardware security module (HSM) designed specifically for Pi based computers. It physically fits the Pi GPIO header, works with Raspbian Stretch and integrates with certain Linux applications including dm-crypt/LUKS for file encryption. All documentation is available on this site, and we suggest you start here: Getting Started

Many of the features of the zymbit security module are similar to a generic “TPM”, such as measured identity, hardware root of trust, key management, data signing and verification. But beware that zymbit security module is NOT a TPM as defined by the Trusted Compute Group. The TCG TMP is specifically designed or laptop devices, not IoT devices.
