Warnings

• AES is currently implemented using LUT, so it might be vulnerable to cache-timing attacks
• RSA and ECC are currently implemented without a cswap, so they might be vulnerable to branch-prediction attacks

Instructions

Requirements

A C99 compiler

Build

Files are created in build

make
build/maid test

Installation

Files are placed in /usr/local

sudo make install
