This is true, but remember that cryptanalyzing the identity function is even easier... The context here is OS -- don't lose that context. Eventually between OS and DANE we should get to where we can just require TLS for SMTP and eventually even authentication of servers. Then indeed using stronger ciphers will matter more than in then context of OS right now. > I used to be highly skeptical of post-quantum crypto, but now I want > something like whyte's PQ mixin stuff today. Yes, sure, but one thing at a time. Nico --
