This repository contains a go library for interacting with TPM 2.0 devices. Some currently supported features are:

 - All authorization modes: cleartext password, HMAC session based and policy session based.
 - All session configurations: salted or unsalted + bound or unbound.
 - Session-based command and response parameter encryption using AES-CFB or XOR obfuscation.
 - Session-based command auditing.
 - Backends for Linux TPM character devices and TPM simulators implementing the Microsoft TPM 2.0 simulator interface.
