1. Install

Get the Dotenvx CLI.

◈ installed (dotenvx)

more install options

2. Encrypt

Encrypt your .env file.

$ dotenvx encrypt

3. Inject

Then inject your encrypted secrets at runtime with dotenvx run.

fn main() {
    let hello = env::var("HELLO").unwrap_or_default();
    println!("HELLO: {}", hello);
}

dotenvx run -- cargo run
