"In the last three articles, I've talked about authentication on
Apache: asking the user for a username and password to get at your

maintenance of your password lists with Perl. Doing it all by hand
can be a real drag."
"Warning: This article assumes that you already have a grasp on
the basics of Perl."
"In case you don't know what Perl is, here's the simple
explanation: it's a programming language. It's a very popular
programming language, favored by folks for doing tasks that require
text manipulation, sockets communication, orchestrating various
applications in some way, and a plethora of other tasks. It is
reputed to be very popular as a CGI programming language also, but
that's only a smidgen of the whole story, and tends to sell Perl
short by people who think, "Oh, that's just a CGI language."
"One of the things that is going to come in very handy in
managing user and password lists is the ability to encrypt a
password. The good news is that Perl has a built-in function to do
just this. It's called crypt. In order to use it, you need to
understand a few things."
