This is an example Rust program for validating a license key. It contains a small command line program which prompts for a license key value and then validates the key using Keygen's software licensing API.

First up, configure a couple environment variables:

# Your Keygen account ID
export KEYGEN_ACCOUNT_ID="YOUR_KEYGEN_ACCOUNT_ID"

You can either run each line above within your terminal session before starting the app, or you can add the above contents to your ~/.bashrc file and then run source ~/.bashrc after saving the file.

Next, install dependencies with cargo:

cargo build

Then run the program:

cargo run
