NATS JWT (Rust)

Crates.io Crates.io Docs.rs

Generate JWTs signed using NKEYs for use with NATS

Supports generating account and user JWTs, operator JWTs are not typically generated on the fly and so aren't supported, although a PR adding support would be accepted.

Example

use nats_jwt::{KeyPair, Token};

// You would probably load the operator's seed via a config and use KeyPair::from_seed
let operator_signing_key = KeyPair::new_operator();

let account_keypair = KeyPair::new_account();
let account_signing_key = KeyPair::new_account();
let account_token = Token::new_account(account_keypair.public_key())
    .name("My Account")
    .add_signing_key(account_signing_key.public_key())
    .max_connections(100)
    .sign(&operator_signing_key);
println!("account_token: {}", account_token);

let user_keypair = KeyPair::new_user();
let user_key_pub = user_keypair.public_key();
let user_token = Token::new_user(account_keypair.public_key(), user_key_pub)
    .bearer_token(true)
    .name("My User")
    .max_subscriptions(10)
    .max_payload(1024 * 1024) // 1MiB
    .allow_publish("service.hello.world")
    .allow_subscribe("_INBOX.>")
    .sign(&account_signing_key);
println!("user_token: {}", user_token);
