Subject: Re: [FD] Hilariously Bad SQRL Implementation

> Why would any sane rational human being implement something from Gibson?

On that note, I did come across the attrition charlatan page after I
started this project. But as far as I'm concerned, I'm only implementing an
Ed25519 signature. That the specific client application is one of Steven
Gibson's brain-children is sort of irrelevant to the scope of my
initiative, but I will certainly treat anything he produces with due
skepticism. That being said, just because he has a history of
fraud/incompetence doesn't mean I will immediately discredit SQRL without
evaluating the spec/src, whenever they're available. It deserves a fair
chance and an uncensored review.

I suppose libsodium/NaCl would fail to meet some peoples' definitions for
"time proven", but the underlying crypto (Curve25519/Ed25519) is being
implemented in various high profile applications (Tor, Cryptocat, etc.) so
if it fails to pass the test of time, a lot of people will end up with egg
on their face.

I fully agree. I wouldn't recommend either the library I'm building nor the
program/protocol that Steven Gibson produces be used in any production
environment until they have been reviewed by competent hackers and
cryptographers.
