In this chapter, we've seen how to work with various encryption technologies that can help us safeguard our secrets. We started with GNU Privacy Guard for encrypting individual files. We then moved on to the disk, partition, and directory encryption utilities. LUKS and eCryptfs are specific to Linux, but we also looked at VeraCrypt, which can be used on any of the major operating systems.

In the next chapter, we'll take an in-depth look at the subject of discretionary access control. I'll see you there.
