4.5. Interesting Projects
I've already mentioned some projects in passing, but no chapter on
source security would be complete without mentioning some of the more interesting projects out there. I'll start with the obvious ones and move on to the more esoteric. This list probably reflects my current
with privacy and anonymity:
Well known, but still essential. This library implements most known cryptographic algorithms, as well as the SSL and TLS protocols. It is very widely used in both free and non-free software, and at the time of this writing was in the final stages of obtaining FIPS-140 certification. http://www.openssl.org.
Of course, we've all known and loved Apache for
. Finally, Apache 2 has HTTPS support out of the box. http://www.apache.org.
A suite of web browser, mail, and news reading software, and
utilities. You probably don't think of this as security software, but it is probably second only to Apache in the number of financial transactions it protects. And it does it with a minimum of fuss. What's more, it isn't plagued with its closed-source rivals' fondness for installing evil software you never intended to install! http://www.mozilla.org.
Implementing the OpenPGP standard under the GPL. Primarily used for email, but also the mainstay for validation of open source packages (using, of course, public key cryptography). http://www.gnupg.org.
Small, but (almost)
. This is a plug-in for the increasingly popular (and, of course, open source) email client, Thunderbird, providing a
streamlined interface for GnuPG. http://enigmail.mozdev.org.
Common Vulnerabilities and Exposures. This is a database of security problems, both commercial and open source. The idea is to provide a uniform reference for each problem, so it's easy to tell if two different people are talking about the same bug. http://cve.mitre.org.
The onion router. Onion routing has been a theoretical possibility for a long time, providing a way to make arbitrary connections anonymously. Zero Knowledge Systems spectacularly failed to exploit it commercially, but now it has come from a most
source: the U.S. Navy. The Navy's funding recently ran out, but the Electronic Frontier Foundation stepped up to take over. Well worth a look. http://tor.eff.org.
