The animated elliptic curve
In the past 5 years I&#x27;ve seen maybe a dozen &quot;how elliptic curves work&quot;, but this is the first to actually illustrate how they work on a small field. I think that&#x27;s key to understanding, seeing it in a small enough field that you can literally see all of the points. Nicely done.<p>If you want to keep going, as an advanced beginner I&#x27;d like to see:<p>Arbitrary bigint math - how do you do Exp&#x2F;Sqrt with arbitrary sized ints? (I&#x27;m familiar with two crypto libs that do this, and MPIs &amp; branches confuse me).<p>Second: why is C25519 faster than SecP256R1 or BrainPool? maybe some insight there? (Isn&#x27;t Ed25519 the signature name? and X25519 the ECDH name?)<p>Greedy of me, but thanks!
