Amazon Cognito Client for Rust

Work in progress...

Usage

extern crate rusoto_core;
extern crate amazon_cognito_rust;

use rusoto_core::{DefaultCredentialsProvider, default_tls_client, Region};
use amazon_cognito_rust::{CognitoUserSession, CognitoUser, AuthDetails, AuthDelegate, Storage};

struct MyStorage {}
impl Storage for MyStorage {
    fn get_item(&self, key: &str) -> Option<String> {
        // read from somewhere
        None
    }
    fn set_item(&self, key: &str, val: &str) {
        // write to somewhere
    }
}

struct MyAuthDelegate {}
impl AuthDelegate for MyAuthDelegate {
    fn on_failure(&self, err: &CognitoError) {
        println!("failed to authenticate user - {:?}", err);
    }
    fn on_success(&self, session: &CognitoUserSession, confirmation_necessary: bool) {
        println!("ACCESS_TOKEN {}", session.access_token.get_jwt_token());
        println!("ID_TOKEN {}", session.id_token.get_jwt_token());
        println!("REFRESH_TOKEN {}", session.refresh_token.get_token().to_string());
    }
}

fn main() {
  let storage = MyStorage {};
  let user = CognitoUser::new(default_tls_client().unwrap(), &storage, USER_POOL_ID, CLIENT_ID, Region::UsEast1);
  user.authenticate_user(&AuthDetails::new(username, password, BTreeMap::new()), &MyAuthDelegate {}).unwrap();

  // to refresh session
  // user.refresh_session(refresh_token);
}

Status

• SRP
• Initiate auth
• Receives device-key, access-token
• User authentication
• Refresh session
• New Password required
• SMS MFS
• Custom Challenge
• Device SRP Auth
