In this hands-on lab, we will create a secondary passphrase for a LUKS-encrypted volume, which can be used to recover the volume's encrypted data if the primary passphrase ever becomes corrupted. Then we'll create a backup of the entire LUKS header, which can be used to recover the encrypted data if the entire LUKS header ever becomes corrupted.

What are Hands-On Labs?

Hands-On Labs are scenario-based learning environments where learners can practice without consequences. Don't compromise a system or waste money on expensive downloads. Practice real-world skills without the real-world risk, no assembly required.
