It's still quite a mess. To compare the two, my TLS suite-choosing code is
more or less:
highestSuite = 0;
foreach suite
suite = readInteger();
if priority( suite ) > priority( highestSuite )

It'll never work, people will clamour for their pet vanity ciphers no matter
what you say

Based on my understanding of zero knowledge proofs and the traditional use
of "zero knowledge" in cryptography, this usage seems... novel, to put it
politely. In the case of SpiderOak, the
I've heard Steve Gibson (grc.com) use the phrase Trust No One (or TNO) when
