lib25519 for ARM
Add 64bit ARM optimisations to lib25519
Modern network protocols rely on elliptic-curve cryptography (ECC) to protect communication against espionage and sabotage. lib25519 is a new software library for the Curve25519 elliptic curve, including the X25519 encryption system and the Ed25519 signature system. Curve25519 is the fastest curve in TLS 1.3, and the only curve in Wireguard, Signal, and many other applications. So far lib25519 has exploited the features of Intel CPUs to provide top speeds for those CPUs, while meeting the security constraint of not leaking secret information through timing. This project will extend lib25519 to target 64-bit ARM CPUs, and in particular the Cortex-A53 CPU, which for instance powers the Raspberry Pi 3.
