Implementing Curve25519/X25519: A Tutorial on Elliptic Curve Cryptography
This tutorial bridges the gap between the mathematics and implementation of elliptic curve cryptography. It is written for readers
who are new to cryptography, and it assumes no more mathematical background than most undergraduate computer science courses. Starting from first principles, this document shows how to derive every line of code in an implementation of the X25519 DiffieHellman key agreement scheme, based on the Curve25519 elliptic curve. The implementation is fast and secure; in particular, it is constanttime to prevent sidechannel attacks.
