If you selected the Encrypt System option, the installer prompts you for a passphrase with which to encrypt the partitions on the system.
Partitions are encrypted using the Linux Unified Key Setup — refer to Appendix C, Disk Encryption for more information.
The dialog contains text boxes to enter a passphrase and to confirm it.
Figure 23.27. Enter passphrase for encrypted partition
Choose a passphrase and type it into each of the two fields in the dialog box. You must provide this passphrase every time that the system boots.
Warning — Do not lose this passphrase
If you lose this passphrase, any encrypted partitions and the data on them will become completely inaccessible. There is no way to recover a lost passphrase.
