Usually my process is very… hammer and drill related - but I have a family member who is interested in taking my latest batch of hard drives after I upgraded.

What are the best (linux) tools for the process? I’d like to run some tests to make sure they’re good first and also do a full zero out of any data. (Used to be a raid if that matters)

Edit: Thanks all, process is officially started, will probably run for quite a while. Appreciate the advice!

    There are many ways to setups full disk encryption on Linux, but the most common all involve LUKS. Providing a password at mount (during boot, for a root partition or perhaps later for a “data” volume) is a but more secure and more frequently done, but you can also use things like smart cards (like a Yubikey) or a keyfile (basically a file as the password rather than typed in) to decrypt.

    So, to actually answer your question, if you dont want to type passwords and are okay with the security implementations of storing the key with/near the system, putting a keyfile on removable storage that normally stays plugged in but can be removed to secure your disks is a common compromise. Here’s an approachable article about it.
