Try the FAQs tutorials listed in the FreeS/WAN (IPsec encrypted tunnels for LInux) documentation: http://www.freeswan.org/freeswan_trees/freeswan-1.91/doc/web.html#crypto.link There's also a glossary with many links to other glossaries: http://www.freeswan.org/freeswan_trees/freeswan-1.91/doc/glossary.html and a bibliography: http://www.freeswan.org/freeswan_trees/freeswan-1.91/doc/biblio.html All these links point to 1.91 versions of docs, which are currently the latest version on the web. FreeS/WAN is actually at 1.94, but there are some web site admin problems so I don't know when up to date docs will appear on the web. - Linux-crypto: cryptography in and on the Linux system Archive: http://mail.nl.linux.org/linux-crypto/
