When an encrypted partition is used, the encryption key is stored in memory (RAM). Retrieving it allows the decryption of the data, making it important to not leave a copy of this key anywhere that a thief of the computer or hard drive can access. On laptops the contents of RAM is stored on the swap partition during hibernation. When using encrypted partitions, also encrypt the swap partition.

The software will then propose to initialise the physical volume with random data (making the localisation of real data more difficult), and will ask you for an "encryption passphrase" (make it hard but not too hard because you will have to enter it every time you boot your computer or access the content of the encrypted partition.
