If you're using systemd you can do this by setting up /etc/crypttab[1] which has a similar format to fstab. For example, here's my swap line:

     eswap   /dev/mapper/vg0-swap    /dev/urandom            swap,cipher=aes-cbc-essiv:sha256

FWIW it's not specific to systemd -- I've been using /etc/crypttab for full-disk encryption (LUKS) for a few years on Ubuntu. The file is consulted when building the initrd, to build in whatever magic is needed to decrypt the disks at boot.
