1//! RFC 7521: JSON Web Token (JWT) Profile for OAuth 2.0 Client Authentication and Authorization Grants
2//!
3//! This module implements private key JWT client authentication, allowing clients
4//! to authenticate using JWTs signed with their private keys.
5//!
6//! ## Enhanced Security Features
7//!
8//! - **SecureJwtValidator Integration**: Uses comprehensive JWT validation with
9//!   enhanced security checks beyond basic signature verification
10//! - **Configurable JTI Cleanup**: Customizable cleanup intervals for managing
11//!   used JWT IDs and preventing replay attacks
12//! - **Advanced Token Management**: Token revocation and validation using the
13//!   enhanced security framework
14//! - **Automatic Cleanup Scheduling**: Integrated cleanup of expired JTIs and
15//!   revoked tokens
16//!
17//! ## Usage Example
18//!
19//! ```rust,no_run
20//! use auth_framework::server::private_key_jwt::{PrivateKeyJwtManager, ClientJwtConfig};
21//! use auth_framework::secure_jwt::{SecureJwtValidator, SecureJwtConfig};
22//! use chrono::Duration;
23//! use jsonwebtoken::Algorithm;
24//!
25//! # async fn example() -> Result<(), Box<dyn std::error::Error>> {
26//! // Create JWT validator with enhanced security
27//! let jwt_config = SecureJwtConfig::default();
28//! let jwt_validator = SecureJwtValidator::new(jwt_config);
29//!
30//! // Create manager with custom cleanup interval
31//! let manager = PrivateKeyJwtManager::new(jwt_validator)
32//!     .with_cleanup_interval(Duration::minutes(30));
33//!
34//! // Configure client for JWT authentication
35//! let config = ClientJwtConfig {
36//!     client_id: "example_client".to_string(),
37//!     public_key_jwk: serde_json::json!({"kty": "RSA", "n": "...", "e": "AQAB"}),
38//!     allowed_algorithms: vec![Algorithm::RS256],
39//!     max_jwt_lifetime: Duration::minutes(5),
40//!     clock_skew: Duration::seconds(60),
41//!     expected_audiences: vec!["https://api.example.com".to_string()],
42//! };
43//!
44//! manager.register_client(config).await?;
45//!
46//! // Authenticate client with JWT assertion
47//! let client_assertion = "eyJ..."; // JWT assertion from client
48//! let auth_result = manager.authenticate_client(client_assertion).await?;
49//!
50//! if auth_result.authenticated {
51//!     println!("Client authenticated successfully");
52//!     // Process authenticated client...
53//! }
54//!
55//! // Perform scheduled cleanup
56//! manager.schedule_automatic_cleanup().await;
57//! # Ok(())
58//! # }
59//! ```
