Fire Auth Token

A Rust library for verifying Firebase ID tokens. It handles token validation, public key caching, and automatic background public key refresh using async operations.

Features

• Verifies Firebase ID token claims
• Caches and refreshes public keys automatically
• Handles various error scenarios during token validation

Installation

Add the package with Cargo:

[dependencies]
fire-auth-token = "0.1.2"

Or run

cargo add fire-auth-token

use fire_auth_token::FirebaseAuth;

#[tokio::main]
async fn main() {
    let project_id = "your-project-id".to_string();
    let auth = FirebaseAuth::new(project_id).await;
    let token = "your-firebase-id-token";
    
    // For regular Firebase tokens
    let user = auth.verify_token::<FirebaseAuthUser>(token).await?;

    // For Google Firebase tokens
    let user = auth.verify_token::<FirebaseAuthGoogleUser>(token).await?;
}
