Mount an encrypted partition on boot

Hint: Always replace "< .... >" with the actual value

1. Find out which name the partition has

$ lsblk

2. Receive UUID of device

$ sudo cryptsetup luksUUID /dev/<result-of-lsblk-command> (e.g. sdb, sda etc.)

3. Add new line to crypttab

$ sudo nano /etc/crypttab
=> New line: "<result-of-lsblk-command> /dev/disk/by-uuid/<result-of-uuid-coomand> none luks"

4. Create directory where partition should get mounted

$ sudo mkdir /mnt/my_encrypted_partition

5. Add new line to fstab

$ sudo nano /etc/fstab
=> New line: "/dev/mapper/<result-of-lsblk-command> /mnt/my_encrypted_partition ext4"

6. Reboot
