Tor Browser 9.5 allows website publishers to advertise their onion service to Tor users by adding HTTP headers. When Onion Location is enabled, Tor users will be prompted to opt-in to upgrade to the onion service.
@torproject How does the naming service work?
@threed The human-memorable/meaningful names feature is still in very early stages of testing with HTTPS Everywhere.
Unfortunately it's not available for general use yet.
@torproject I'm more asking whether this DNS is in any way decentralized or based on some interesting cryptographic primitives? Or is it just a single spot that stores the mapping in plaintext?
Now, onion service administrators who want to add an extra layer of security to their website can set a pair of keys for access and control.
