A Guide to Notable Onion Web Pages and Their Uses

What Are Onion Web Pages and How Do They Work

.onion domains are specific to the Tor network, enabling access to onion services that maintain user and operator anonymity through end-to-end encryption. Unlike traditional websites on the surface web, onion services do not require HTTPS, as the Tor network inherently secures connections¹.

Tor operates by routing internet traffic through a series of volunteer-run relays. When a user connects to an onion service, their request travels through at least six relays, ensuring that the data does not exit the Tor network, which enhances privacy². This routing process obscures both the user's identity and the location of the service being accessed, distinguishing it from standard web browsing.

.onion addresses have evolved, with the current v3 format consisting of 56 characters that encode a service's public key. This format eliminates the need for domain name purchases and provides cryptographic verification of the service's identity². In contrast, the older v2 addresses, which had only 16 characters, are no longer supported on the current Tor network¹. Examples of v3 addresses include ProPublica's onion site (example: www.propub3r6espa33w.onion) and the Hidden Wiki (example: wikitjerrta4qgz4.onion).

.onion addresses change frequently due to security measures; if an address is compromised, the service operator may generate a new one to maintain safety¹. This dynamic nature necessitates caution when accessing onion services, as a slight alteration in an address can lead to a completely different and potentially harmful site.
