Around four years ago, I wrote a blog post about creating vanity
.oniondomains for Tor. To recap,
.oniondomains are special domains understood by Tor, and when visiting these sites, traffic never leaves the Tor network and is end-to-end encrypted, just as if you were to use HTTPS. Furthermore, the server’s identity is completely protected, if you are into that sort of thing. Also, the domain name is linked to the server’s public key fingerprint, and so knowing the
.oniondomain is sufficient to authenticate the server and preventing any MITM attacks or certificate authority compromises that could happen with HTTPS.
