#NewsBytesExplainer: Everything you need to know about 'dark web'

In simplest terms, the dark web, or darknet, is a collection of thousands of websites with encrypted content.

It exists on overlay networks that use the traditional internet but are accessible only with a suite of specific secure-browsing tools.

For instance, you could use Tor (the onion router) to securely browse sites making up the dark web.

The secure tools hide the IP addresses of the servers running dark web sites as well as the user network traffic going to and from them.

This way, they enable a system that allows you to browse with complete anonymity. There is no risk of ISPs logging your internet activity on the directive of the government or marketers and VPN providers tracking you.

To ensure anonymity and provide access to protected dark web websites, Tor and other tools encrypt the web traffic in layers and then bounce it randomly through computers around the world.

This prevents third-parties, including search engines, from decrypting the origin and the destination of the traffic, seeing who is visiting the site, and where the site's servers are located, among other things.

The fact that dark web sites are untrackable and can be accessed with complete anonymity evidently invites illegal uses.

People often create dark web marketplaces to sell drugs, guns, identities, credit card numbers, stolen user data, etc. while shielding their servers from identification and takedown by law enforcement.

Meanwhile, people using Tor access these sites to covertly purchase illegal items by paying bitcoins.

However, the anonymous and private nature of the dark web can also be used for legitimate reasons.

For instance, tech companies, news organizations, universities, and activists in repressive regimes use the dark web for anonymous whistleblowing as well as protection from government-backed censorship and surveillance.

There are also many who use Tor and the dark web simply for being private and anonymous online.

That said, it must be noted that accessing dark web is not illegal but exploiting that access for shady activities, like buying/selling child pornography, is.

So, as long as you are using the dark web for innocuous/legal purposes, you will not get into any trouble.

The UN recognizes encryption as a fundamental human right, while the US State Department helps fund the Tor project.
