Dear Jim,
Tor ("The Onion Router") has
been up and running for some time. It's a free and highly secure system
for anonymous browsing. It requires installation
of free, open source software on the host machine.
Also of potential interest is the current release of Freenet, which supports
a "scalable darknet:"
A freeware, open source distribution
of PGP (named,
appropriately, GPG).
A GPG
for Windows front end.
TrueCrypt (a freeware/open
source hard drive encryption/steganography program)
The Electronic Privacy
Information Center (EPIC) tools page
Hushmail:
secure, free web mail
Secure, free hard drive/file
erasure
Disclaimer and warning: Strong cryptography isn't
legal everywhere. The United States, for example, still regards some
types of cryptographic algorithms
as munitions, and export is forbidden. Know your country's laws before you
proceed. Cryptography isn't a panacea for our loss of privacy in the digital
age. It is, however, a very powerful tool to put an envelope back on your mail,
a lock on your computer's "filing cabinet," to destroy sensitive
files or to send a letter without a return address - all things our parents
took for granted. Learn its limits and use it wisely for your own sake and
everyone else's. Do not attempt to send threats, traffic in drugs or child
pornography, plan acts of terrorism or engage in other crimes using crypto.
Sooner or later, you'll draw attention to yourself and the full weight of the
law will come down, hard. You will be caught, you will be prosecuted, you will
be imprisoned. Period. Regards, - Moriarty
