[curves] Intro

[Ron Garret]

Hello,

I’ve been lurking on this list for a while and I thought I would introduce myself because I get the impression that many of you already know each other, and I’m not sure if it’s really appropriate for me to be here.  I’m not a cryptographer, and most of the discussion on this list so far has been way over my head.  But I have studied some crypto, I have a basic understanding of how elliptic curves work, and I’m a big fan of the technology.  If you want some idea of where I’m at in my studies, here’s a little primer I wrote a while ago, as part of a series of blog posts on applying digital signatures to the problem of credit card fraud:

I’ve produced a few of my own implementations of curve25519 and ed25519 as exercises.  The most interesting one (IMO) runs on on a teensy3 (http://www.pjrc.com/store/teensy3.html) as a proof-of-concept that this device could possibly be used as an HSM.  If anyone here is interested I would be happy to release the code.  In fact, I would really appreciate a code review from someone who actually knows what they are doing.
