Today we are announcing a new privacy feature coming to Kagi Search. Privacy Pass is an authentication protocol first introduced by Davidson and recently standardized by the IETF as RFCs. At the same time, we are announcing the immediate availability of Kagi’s Tor onion service.
In general terms, Privacy Pass allows “Clients” (generally users) to authenticate to “Servers” (like Kagi) in such a way that while the Server can verify that the connecting Client has the right to access its services, it cannot determine which of its rightful Clients is actually connecting. This is particularly useful in the context of a privacy-respecting paid search engine, where the Server wants to ensure that the Client can access the services, and the Client seeks strong guarantees that, for example, the searches are not associated with them.
