The Darknet, also known as the Dark Web, is an encrypted part of the Internet that is not freely accessible and is not indexed by search engines. Access to the darknet is possible only with a special browser, with special software or appropriate authorization.
The darknet is a loose network of many private computers that are interconnected as a peer-to-peer network and between which data is often transmitted in encrypted form. The darknet is accessed via the Tor program, where TOR stands for The Onion Router (TOR). The Tor program supports covert services where the sender and receiver remain anonymous.
Since the connection data and the connection paths of the Darknet cannot be traced, the Darknet is used both for legal purposes and for illegal offers. Legal applications involve the anonymization of individuals who are not identifiable. This advantage can be used for whistleblower protection. For example, whistleblowers, dissidents and organizations critical of the government. They can send their information via the darknet without being detected. The second illegal area concerns crime, drug and arms trafficking, as well as cybercrime with offers for pirated copies, spams, mailbombing, password cracking, hacking and hacking as a service( HaaS) and other illegal activities.
In the Darknet, all the services of the Internet, such as file transfer and e-mail, can be realized. Darknet websites are not indexed by search engines. To ensure completely anonymous communication, Tor addresses are used instead of mail addresses. For security, Tor mails are encrypted using the PGP algorithm.
