I wrote a long article for TidBITS about SSL/TLS, attempting to explain it to a lay audience. I wrote another piece for admins on how to use CA.pl, which TidBITS didn't pick up, and a third piece on a couple shell scripts I wrote to help run a Certificate Authority, called cert.command & sign.command. I hope you find them interesting and useful.
