So I am trying to encrypt my file system and use the TPM for key storage, so it doesn't require a password on boot, but my device does not have a TPM. Instead it has PTT (Intel platform trust technology - a firmware replacement of TPM) I was trying to follow a tutorial, but I am confused as to how to do this with a PTT instead of a TPM. Any help would be greatly(!) appreciated. I am running a Kali distro if that makes any difference.

If this should go in a different section other than hardware, please let me know!
