In this blog post, we’ll explore how to bind LUKS encryption to a TPM using the Clevis tool on Linux. We’ll provide technical details and a step-by-step guide for using Clevis to create a TPM-bound PIN and encrypt the LUKS key, as well as an explanation of what PCR IDs are and how they’re used in the process. So, let’s get started! First, we’ll take a closer look at what Clevis is and how it works with LUKS encryption and TPMs.
