Loads a LUKS tpm2 key during inital ramdisk to auto decrypt drive under secure conditions
This setup contains hooks to be used with mkinitcpio
To setup the hook run make install
as root and then add the tpm2
hook before the encrypt
hook in /etc/mkinitcpio.conf
Make sure the tpm2-tools
are installed so keys can be generated and unsealed
For arch linux, its as easy as pacman -S tpm2-tools
Before you can run the script make sure the device
, slot
, keyloc
, and pcr
, variables at the top of the script.
device
- The block device the LUKS partition is located at
slot
- The key slot that the key will be put in (WARNING this slot will be overwritten if it contains data)
keyloc
- The tpm location the key will be sealed in (default is fine usually)
pcr
- The pcr rules for storing the key (default is fine usually)
Key generation is automatic with the gentpm.sh
script
Run make build
as root, this will generate and store the keys, and also rebuild the ramdisk
