SIDH C Reference

A reference implementation of the Supersingular Isogeny Key Exchange System in C.

Installation

You can clone this repo using

git clone https://github.com/sidh-crypto/sidh-c-reference.git

or download the zip file. You will also need a recent version of the GNU GMP.

Demo

In a terminal:

cd sidh/
make

and in the test directory you can do

./test_key_exchange 

This will run a key exchange demo for a 46bit prime. There are four sample parameter sets in the test directory called public_params_*. For example, to run the demo for a 521bit prime you can do

./test_key_exchange public_params_521

You can test your own parameter set, provided it is in the same format as the sample sets.
