This repo is an example of adapting the Chaum–Pedersen protocol for 1 factor authentication.

You can run the client-server authentication in a few different ways:

• Nix
• Rust
• Docker

Full instructions on how to install Nix can be found here but the recommended why is:

sh <(curl -L https://nixos.org/nix/install) --daemon

There are a few ways to enable flakes depending on environment; they are listed here.

After flakes have been enabled, the environment can be bootstrapped by running:

nix develop --impure

Note: You will need to do this in two different terminal windows; one for the server and one for the client

In the first terminal simply run:

server

This will run the server half locally on port 8080.

In the second window, you will need to register your secret password first. This can be done by running:

register <username>

You will be asked to enter a secret password that corresponds to the username.

Once registered, you can attempt to authenticate by running:

authenticate <username>

You will once again be asked to enter the secret password, and if it is the same password that you registered, you should get a successful authentication message.
