There are a lot of reasons to like the “25519” key technology, and while this talks about interesting work at AWS to make it safer and faster, it also has maybe the best basic intro to elliptic-curve math that I’ve read anywhere.

I am defintely a fan of 25519. Better performance, better security per bit, and with constant time coding, it may not leak via side channel.
So, I would be concerned with anyone trying to 'improve' it. Especially AWS.

@SpaceLifeForm Um read the blog piece.

@timbray How confident can we be, 20ish years after its introduction, that it is still meaningfully effective?
-
@mhoye I lack first-hand expertise. But real experts who seem to me smart and honest are pretty confident.
