There is the source code. It needs patched util-linux(-ng) package to get working. Also you should not use (crypt-)loop because it conflicts with it (see README inside tar ball). It also provides a really simple swap encryption:
- /etc/fstab -
/dev/blaX none swap sw,loop=/dev/loop0,encryption=AES256,itercountk=100 0 0
This will make sure that everytime you bootup your system a new encryption is setup with an iteration of 100 (still performant enough for most things).

Thank you for the explanation. Maybe it should be added to the wiki?
