Description
A simple validation test case for Clevis on Fedora IoT Edition.
Setup
Install a system with an encrypted root filesystem. See this testcase for further details.
How to test
Verify decryption is working via TPM2
echo foo | clevis encrypt tpm2 '{}' | clevis decrypt
Get the UUID of the encrypted device
UUID=$(lsblk | grep luks | sed 's/^.*luks-//' | cut -d ' ' -f1) DEV=$(blkid --uuid $UUID)
Check encryption details of the device
cryptsetup luksDump $DEV
Verify the passphrase before setting
cryptsetup luksOpen --test-passphrase --key-slot 0 $DEV && echo correct
Setup Clevis to decrypt via TPM2 on boot
clevis luks bind -f -k- -d $DEV tpm2 '{}' <<< $YOUR_PASSPHRASE
