Requirements

Dependency	Version
rustup	1.50.0
openssl	1.1.1

Setup

Step 1: Generate an X25519 key pair

openssl genpkey -algorithm x25519 -out x25519_private_key.pem
openssl pkey -in x25519_private_key.pem -pubout -out x25519_public_key.pem

Make sure you're pointing to the right openssl installation (e.g. macOS provides an old default implementation that doesn't have the X25519 algorithm).

Step 2: Build the project

cargo build

The Linux Rust installer assumes that you already have a C linker installed. If this is not the case you'll see error: linker 'cc' not found. To fix this, run:

apt update
sudo apt install build-essential

Step 3: Run it

cargo run --release
