> TLS supports a "NULL" cipher in certain cipher suites for signed-only transmissions, but mainstream server and client support are limited (for good reasons). IIRC Windows Update used to do that in XP days, to guarantee responses were signed but to alleviate the pressure of encryption from the CDNs handling updates at the time. (When SSL/TLS was fairly heavy, and Windows Update traffic was 10s of % of internet traffic)
