Is X25519 Associative? Sometimes!

X25519 is a simple Elliptic Curve Diffie-Hellman ECDH function: it takes a scalar a fancy name for an integer1 and an elliptic curve point, and it multiplies the elliptic curve point by the scalar. Point additions and multiplications work modulo the order of the point, just like hours on a watch...
