This page explains how to sign user SSL certificates, among other things.
Introduction
The page [http://www.rajeevnet.com/crypto/ca/ca-paper.html] was very helpful in figuring out which commands to run. I took the initial copy of the OpenSSL configuration file from [http://sial.org/howto/openssl/ca/openssl.cnf], and then added things to it from the first link.
All of our CA stuff is stored at /var/local/lib/ca on deleuze.
The public-accessible CA stuff is at /afs/hcoop.net/user/h/hc/hcoop/public_html/ca, or [http://deleuze.hcoop.net/ca].
