A Detailed Elliptic Curve Cryptography Tutorial
This looks nice.  Too bad I care more about Montgomery and Twisted Edwards curves (everyone say curve255129 and edDSA are great, and I believe them).<p>I&#x27;m looking for <i>one</i> thing, which I hope should speed up signature and verification speed with very little bloat: converting a Twisted Edwards point to Montgomery space, then back (with that sign recovery trick after the Montgomery ladder).<p>Reading (and trying to apply) the relevant papers has been frustrating so far (I get wrong results), and I can&#x27;t find code (or pseudo-code) I can use.  Have someone implemented this?
