12.4. Understanding Encryption

Fedora includes functions to encrypt your storage. You may find this function useful if you have a laptop or if you worry about your disk storage falling out of your control. This disk encryption requires you to provide an additional passphrase at boot time or whenever you first access the disk storage.

You may choose to encrypt either all partitions, or only selected ones. A typical use case includes encrypting partitions containing /home, /var, and /tmp, along with the swap partition. There is usually no need to encrypt /usr, since this directory usually contains only system executables and libraries that have no intrinsic privacy value. The /boot partition is never encrypted and should not be used for sensitive data.

[Note] Encrypted Storage Performance

Storage encryption creates a slight performance decrease. You may wish to weigh this drawback against the benefits of security and privacy that encryption provides.

To make the encryption effective, choose a good passphrase. Note the use of the term "passphrase", as opposed to the term "password." This is intentional. Utilizing a phrase containing multiple words increases the security of your data.

The encryption provided uses the Linux Unified Key System (LUKS) for encryption. For more information on LUKS, refer to
