Recover Data from an Encrypted File System on Linux

The Linux Unified Key Setup (LUKS) lets you add an encrypted layer to your file systems as an added protection for your data. When using LUKS, you can store up to eight keys to unencrypt the file system — but even with up to eight keys, sometimes things go wrong and access is lost. In this lab, you will recover data from an encrypted file system without any functioning keys. _This lab is not approved or sponsored by Red Hat._
