Read/Write password to TPM
# Check TPM version
# Install TPM 1.2 dependancies
apt install tpm-tools
# My tpm didn't have a one time configuration done in the factory and required me to run an additional command. I had output like:
# Tspi_TPM_TakeOwnership failed: 0x00000023 - layer=tpm, code=0023 (35), No EK
# https://sourceforge.net/p/trousers/mailman/message/19415379/ instructed me to run:
