crypto patch

Hola~

Rookie question here. I'm trying to setup an encrypted filesystem as per:

    http://www.linuxdoc.org/HOWTO/Loopback-Encrypted-Filesystem-HOWTO-3.html

The first step is installing the latest crypto patch. How do I install the
"latest crypto patch" using apt-get?

My sources.list include:

deb http://http.us.debian.org/debian unstable main contrib non-free
deb http://non-us.debian.org/debian-non-US unstable/non-US main contrib
non-free
deb http://security.debian.org stable updates

deb-src http://http.us.debian.org/debian unstable main contrib non-free
