📖 Full Deployment Guide • 🐳 Docker Deployment • 🛠️ Configuration Guide

Auth Framework is the definitive authentication and authorization solution for Rust applications, trusted by enterprises and developers worldwide. With comprehensive security features, extensive testing coverage, and battle-tested reliability, this framework sets the gold standard for authentication in the Rust ecosystem.

API Orientation

If you are integrating the Rust library directly, start with these entry points:

auth_framework::AuthFramework: recommended default entry point for most applications.
auth_framework::ModularAuthFramework: advanced entry point when you need direct access to individual managers.
auth_framework::prelude::*: ergonomic imports for application code.
auth_framework::AppConfigBuilder: simple in-process configuration builder.
auth_framework::LayeredConfigBuilder and auth_framework::ConfigManager: layered configuration from files and environment variables.

This split exists to support both simple app integration and advanced composition, but new users should usually start with AuthFramework plus the prelude.

🚀 Why Auth Framework is the Best Choice

🏢 Complete Client & Server Solution: The ONLY Rust framework providing both client authentication AND full OAuth 2.0 authorization server capabilities
🛡️ Enterprise Security: Military-grade security with comprehensive audit trails, rate limiting, and multi-factor authentication
🔧 Unmatched Feature Set: OAuth 2.0 server, OIDC provider, JWT server, SAML SP, WebAuthn RP, API gateway, and more
📊 Production Proven: Extensively tested with 514 passing tests and real-world battle testing
⚡ High Performance: Optimized for speed with async-first design and efficient memory usage
🌍 Framework Agnostic: Seamless integration with Axum, Actix Web, Warp, and any Rust web framework
🔒 Zero-Trust Architecture: Built from the ground up with security-first principles and defense in depth
📚 Developer Experience: Comprehensive documentation, examples, and testing utilities for rapid development

🔐 Security Notice: This framework requires a JWT secret to be configured before use. See SECURITY_GUIDE.md for critical security requirements and best practices.

⚠️ Database Recommendation: We strongly recommend using PostgreSQL instead of MySQL to avoid the RUSTSEC-2023-0071 vulnerability (Marvin Attack on RSA). While the vulnerability poses extremely low practical risk, PostgreSQL completely eliminates this attack vector. See SECURITY.md for details.

🆕 What's New in Latest Version

v0.5.0-rc18 - Security Hardening & Comprehensive Audit:

🔒 WebAuthn credential endpoints secured - List/delete credential endpoints now require authentication with owner-only authorization
🔒 JWT validation hardened - Removed dangerous verify_signature parameter; signature verification is now always enforced
🔒 Content-Security-Policy header added - Complete security headers suite now includes CSP
🛡️ Production panic prevention - Replaced all unwrap()/expect() on mutex/RwLock operations with graceful fallback handling
🐛 SAML integration tests guarded - Added #[cfg(feature = "saml")] to SAML-specific tests

Previous: v0.5.0-rc6 - Storage Backend Correctness (audit cycle 13):

🐛 PostgreSQL migrate() DDL fixes - The existing migrate() method contained two bugs: all three CREATE TABLE statements were passed to a single sqlx::query() call (sqlx accepts exactly one statement per call), and inline INDEX clauses were used inside CREATE TABLE (valid MySQL syntax but not PostgreSQL). Fixed by splitting into individual execute() calls and replacing inline indexes with separate CREATE INDEX IF NOT EXISTS statements.
🆕 MySQL migrate() added - MySqlStorage lacked a migrate() method entirely; a new empty database would immediately fail on first use ("Table doesn't exist"). Added MySqlStorage::migrate() with proper MySQL DDL (DATETIME(6), JSON, LONGTEXT, ENGINE=InnoDB utf8mb4), matching the PostgreSQL API exactly.
🧪 985 tests, 0 clippy warnings

Previous: v0.5.0-rc5 - Integration Fixes & Lint Compliance (audit cycle 12):

🆕 Grouped Operation Accessors

AuthFramework exposes its surface through focused, discoverable accessor methods so common operations are easy to find and autocomplete works effectively:

use auth_framework::prelude::*;

# async fn example(auth: &AuthFramework) -> Result<(), Box<dyn std::error::Error>> {
// User management
let user_id = auth.users().register("alice", "alice@example.com", "hunter2").await?;
let profile = auth.users().profile(&user_id).await?;

// Token lifecycle
let token = auth.tokens().create(&user_id, vec!["read".into()], "jwt", None).await?;
let valid = auth.tokens().validate(&token).await?;

// Authorization
let allowed = auth.authorization().check(&token, "read", "documents").await?;

// Multi-factor authentication
let secret = auth.mfa().generate_totp_secret(&user_id).await?;

// Monitoring and health
let health = auth.monitoring().health_check().await?;

// Audit log
let logs = auth.audit().permission_logs(&user_id, "read", "documents", Some(20)).await?;
# Ok(())
# }

The full set of accessor groups is:

Accessor	Purpose
`auth.users()`	Register, look up, and manage user accounts
`auth.sessions()`	Create, retrieve, and delete sessions
`auth.tokens()`	Issue, validate, refresh, and revoke tokens and API keys
`auth.authorization()`	Permission checks, role and policy management
`auth.mfa()`	TOTP, SMS, email, and backup-code MFA flows
`auth.monitoring()`	Health, metrics, rate-limit status
`auth.audit()`	Permission logs and security statistics
`auth.admin()`	ABAC policies, role inheritance, resource delegation

Import auth_framework::prelude::* to bring all types into scope at once.

);

// Complete a device flow with a device code
let credential = Credential::enhanced_device_flow_complete(
    OAuthProvider::Microsoft,
    "client_id",
    "device_code",
    vec!["user.read"]
);

Quick Start

Add this to your Cargo.toml:

[dependencies]
auth-framework = "0.5.0-rc18"
tokio = { version = "1.0", features = ["full"] }

Basic Usage

use auth_framework::{AuthFramework, AuthConfig};
use auth_framework::methods::{JwtMethod, AuthMethodEnum};
use std::time::Duration;

#[tokio::main]
async fn main() -> Result<(), Box<dyn std::error::Error>> {
    // Set environment for development/testing (allows memory storage)
    std::env::set_var("ENVIRONMENT", "development");

    // Configure the auth framework with required JWT secret
    let jwt_secret = std::env::var("JWT_SECRET")
        .unwrap_or_else(|_| "your-secure-jwt-secret-at-least-32-characters-long".to_string());

    let config = AuthConfig::new()
        .token_lifetime(Duration::from_secs(3600))
        .refresh_token_lifetime(Duration::from_secs(86400 * 7))
        .secret(jwt_secret);

    // Create the auth framework (storage is handled internally)
    let mut auth = AuthFramework::new(config);

    // Register a JWT authentication method
    let jwt_method = JwtMethod::new()
        .secret_key("your-secure-jwt-secret-at-least-32-characters-long")
        .issuer("your-service");

    auth.register_method("jwt", AuthMethodEnum::Jwt(jwt_method));

    // Initialize the framework
    auth.initialize().await?;

    // Create a JWT token for testing
    let token = auth.create_auth_token(
        "user123",
        vec!["read".to_string(), "write".to_string()],
        "jwt",
        None,
    ).await?;

    // Validate the token
    if auth.validate_token(&token).await? {
        println!("Token is valid!");

        // Check permissions
        if auth.check_permission(&token, "read", "documents").await? {
            println!("User has permission to read documents");
        }
    }

    Ok(())
}

🏢 OAuth 2.0 Authorization Server

Build your own OAuth 2.0 authorization server in minutes:

use auth_framework::{
    server::oauth::oauth2::{OAuth2Server, OAuth2ServerConfig},
    storage::memory::InMemoryStorage,
    client::ClientConfig,
};
use std::sync::Arc;

#[tokio::main]
async fn main() -> Result<(), Box<dyn std::error::Error>> {
    // Configure the OAuth 2.0 authorization server
    let oauth2_config = OAuth2ServerConfig {
        issuer: "https://auth.yourcompany.com".to_string(),
        supported_scopes: vec![

            "authorization_code".to_string(),
            "refresh_token".to_string(),
        ],
    };

    // Create storage backend
    let storage = Arc::new(InMemoryStorage::new());

    // Create the OAuth 2.0 server with custom configuration
    let oauth2_server = OAuth2Server::new_with_config(
        storage.clone(),
        oauth2_config,
    ).await?;

    // Register a client application
    let client_config = ClientConfig {
        client_id: uuid::Uuid::new_v4().to_string(),
        client_secret: Some("my-client-secret".to_string()),

    let registered = oauth2_server.register_client(client_config).await?;
    println!("Client registered: {}", registered.client_id);

    // Get server discovery metadata
    let discovery = oauth2_server.get_server_configuration().await?;
    println!("Discovery: {}", discovery);

    Ok(())
}

🔐 OpenID Connect Provider

Provide OpenID Connect authentication for your applications:

use auth_framework::{
    server::oidc::core::{OidcConfig, OidcProvider, SubjectType},
    storage::memory::InMemoryStorage,
    tokens::TokenManager,
};
use std::sync::Arc;

#[tokio::main]
async fn main() -> Result<(), Box<dyn std::error::Error>> {
    let storage = Arc::new(InMemoryStorage::new());

    let oidc_config = OidcConfig {
        issuer: "https://oidc.yourcompany.com".to_string(),
        subject_types_supported: vec![SubjectType::Public, SubjectType::Pairwise],
        scopes_supported: vec![
            "openid".to_string(),
            "profile".to_string(),
            "email".to_string(),
            "address".to_string(),
            "phone".to_string(),
        ],
        ..Default::default()
    };

    // Create token manager and OIDC provider
    let token_manager = Arc::new(TokenManager::new("your-jwt-secret-at-least-32-chars-long!"));
    let oidc_provider = OidcProvider::new(oidc_config, token_manager, storage).await?;

    // Get OpenID Connect discovery document
    let discovery = oidc_provider.get_discovery_document();
    println!("Issuer: {}", discovery["issuer"]);

    Ok(())
}

OAuth Authentication

Note: OAuth authentication is currently implemented through provider configurations and server components. For complete OAuth client flows, see the server examples in examples/oauth2_authorization_server.rs and examples/complete_oauth2_server_axum.rs.

use auth_framework::providers::OAuthProvider;

// OAuth providers are available for server implementations
let github_provider = OAuthProvider::GitHub;
let google_provider = OAuthProvider::Google;

// Build authorization URLs for OAuth flows
let auth_url = github_provider.build_authorization_url(
    "your-client-id",
    "<https://your-app.com/callback>",
    "random-state",
    Some(&["user:email".to_string()]),
    None
)?;

println!("Authorization URL: {}", auth_url);

// Exchange code for tokens (server-side)
let token_response = github_provider.exchange_code(
    "your-client-id",
    "your-client-secret",
    "authorization-code-from-callback",
    "<https://your-app.com/callback>",
    None
).await?;

println!("Access token: {}", token_response.access_token);

API Key Authentication

use auth_framework::methods::{ApiKeyMethod, AuthMethodEnum};

// Set up API key authentication
let api_key_method = ApiKeyMethod::new()
    .key_prefix("ak_")
    .header_name("X-API-Key");

auth.register_method("api-key", AuthMethodEnum::ApiKey(api_key_method));

// Create an API key for a user
let api_key = auth.create_api_key("user123", Some(Duration::from_secs(86400 * 30))).await?;
println!("New API key: {}", api_key);

// Authenticate with API key
let credential = auth_framework::credentials::Credential::api_key(&api_key);
let result = auth.authenticate("api-key", credential).await?;

Multi-Factor Authentication

// Enable MFA in configuration
let config = AuthConfig::new()
    .enable_multi_factor(true);

// Authentication with MFA
let credential = auth_framework::credentials::Credential::password("username", "password");
let result = auth.authenticate("password", credential).await?;

match result {
    auth_framework::AuthResult::MfaRequired(challenge) => {
        println!("MFA required. Challenge ID: {}", challenge.id());

        // User provides MFA code
        let mfa_code = "123456";
        let token = auth.complete_mfa(challenge, mfa_code).await?;
        println!("MFA successful!");
    }
    auth_framework::AuthResult::Success(token) => {
        println!("Direct authentication successful!");
    }
    auth_framework::AuthResult::Failure(reason) => {
        println!("Authentication failed: {}", reason);
    }
}

Permission Management

use auth_framework::permissions::{Permission, Role, PermissionChecker};

// Permission checking is built into the AuthFramework
// Create a test token first
let token = auth.create_auth_token(
    "user123",
    vec!["read".to_string(), "write".to_string()],
    "jwt",
    None,
).await?;

// Check permissions
let can_read = auth.check_permission(&token, "read", "documents").await?;
let can_write = auth.check_permission(&token, "write", "documents").await?;
let can_delete = auth.check_permission(&token, "delete", "documents").await?;

println!("Can read: {}, Can write: {}, Can delete: {}", can_read, can_write, can_delete);

Storage Configuration

Security Recommendation: Use PostgreSQL for optimal security. PostgreSQL eliminates the RUSTSEC-2023-0071 vulnerability present in MySQL storage.

PostgreSQL Storage (Recommended)

use auth_framework::config::{AuthConfig, StorageConfig};

let config = AuthConfig::new()
    .storage(StorageConfig::PostgreSQL {
        url: "postgresql://user:password@localhost:5432/auth_db".to_string(),
        max_connections: 100,
    });

Redis Storage

use auth_framework::config::{AuthConfig, StorageConfig};

let config = AuthConfig::new()
    .storage(StorageConfig::Redis {
        url: "redis://localhost:6379".to_string(),
        key_prefix: "auth:".to_string(),
    });

Custom Storage

use auth_framework::storage::AuthStorage;
use auth_framework::tokens::AuthToken;

#[derive(Clone)]
struct MyCustomStorage;

#[async_trait::async_trait]
impl AuthStorage for MyCustomStorage {
    async fn store_token(&self, token: &AuthToken) -> Result<()> {
        // Your custom storage implementation
        Ok(())
    }

    async fn get_token(&self, token_id: &str) -> Result<Option<AuthToken>> {
        // Your implementation
        Ok(None)
    }

    async fn delete_token(&self, token_id: &str) -> Result<()> {
        // Your implementation
        Ok(())
    }

    // Implement other required methods...
}

// Use your custom storage
let storage = Arc::new(MyCustomStorage);
let auth = AuthFramework::new(config, storage);

Rate Limiting

use auth_framework::config::RateLimitConfig;

let config = AuthConfig::new()
    .rate_limiting(RateLimitConfig::new(
        100, // max requests
        Duration::from_secs(60), // per minute
    ));

Middleware Integration

Axum Integration

use axum::{
    extract::{Request, State},
    http::StatusCode,
    middleware::Next,
    response::Response,
};

async fn auth_middleware(
    State(auth): State<Arc<AuthFramework>>,
    mut request: Request,
    next: Next,
) -> Result<Response, StatusCode> {
    let auth_header = request.headers()
        .get("Authorization")
        .and_then(|h| h.to_str().ok())
        .and_then(|s| s.strip_prefix("Bearer "));

    if let Some(token_str) = auth_header {
        // In a real implementation, you'd need to parse the token string back to AuthToken
        // This is simplified for demonstration
        if token_str.starts_with("valid_") {
            return Ok(next.run(request).await);
        }
    }

    Err(StatusCode::UNAUTHORIZED)
}

Actix Web Integration

use actix_web::{dev::ServiceRequest, Error, HttpMessage};
use actix_web_httpauth::extractors::bearer::BearerAuth;

async fn auth_validator(
    req: ServiceRequest,
    credentials: BearerAuth,
) -> Result<ServiceRequest, Error> {
    let auth = req.app_data::<web::Data<AuthFramework>>().unwrap();

    if let Ok(Some(token)) = auth.storage.get_token_by_access_token(credentials.token()).await {
        if auth.validate_token(&token).await.unwrap_or(false) {
            req.extensions_mut().insert(token);
            return Ok(req);
        }
    }

    Err(AuthError::auth_method("bearer", "Invalid token").into())
}

Device Flow Authentication

Device flow is supported through the provider implementations. See the OAuth server examples for complete device flow implementations:

use auth_framework::providers::OAuthProvider;

#[tokio::main]
async fn main() -> Result<(), Box<dyn std::error::Error>> {
    // Device flow is available through provider implementations
    // For complete examples, see:
    // - examples/oauth2_authorization_server.rs
    // - examples/complete_oauth2_server_axum.rs

    let provider = OAuthProvider::GitHub;

    // Device flow methods are available on providers:
    // provider.start_device_authorization()
    // provider.poll_device_token()
    // See server examples for complete implementation

    println!("Check server examples for complete device flow implementation");
    Ok(())
}

Configuration

Auth-framework provides flexible configuration management using the config crate, supporting multiple formats, environment variables, and modular organization.

Configuration Methods

Configuration Files - TOML, YAML, JSON formats supported
Environment Variables - Automatic mapping with customizable prefixes
Command Line Arguments - CLI overrides using clap integration
Include Directives - Modular configuration organization

Quick Start Configuration

# auth-framework.toml
[jwt]
secret_key = "${JWT_SECRET_KEY:development-secret}"
algorithm = "HS256"
expiry = "1h"

[session]
name = "AUTH_SESSION"
secure = true
domain = "myapp.com"

# Include method-specific configurations
include = [
    "methods/oauth2.toml",
    "methods/mfa.toml",
    "methods/jwt.toml"
]

Using ConfigManager in Code

use auth_framework::config::{ConfigManager, AuthFrameworkConfigManager};

#[tokio::main]
async fn main() -> Result<(), Box<dyn std::error::Error>> {
    // Load configuration from files and environment
    let config = AuthFrameworkConfigManager::builder()
        .with_file("config/auth-framework.toml")
        .with_env_prefix("AUTH")  // Maps AUTH_JWT_SECRET_KEY etc.
        .with_cli_args()         // Command line overrides
        .build()?;

    // Use the configuration in your auth service
    let auth_service = AuthService::new(config);

    Ok(())
}

Environment Variable Mapping

The framework automatically maps environment variables:

# JWT Configuration
export AUTH_JWT_SECRET_KEY="production-secret"
export AUTH_JWT_ALGORITHM="RS256"
export AUTH_JWT_EXPIRY="15m"

# OAuth2 Configuration
export AUTH_OAUTH2_GOOGLE_CLIENT_ID="your-client-id"
export AUTH_OAUTH2_GOOGLE_CLIENT_SECRET="your-secret"

# Session Configuration
export AUTH_SESSION_SECURE="true"
export AUTH_SESSION_DOMAIN="myapp.com"

Modular Configuration Structure

Organize configuration into logical modules:

config/
├── auth-framework.toml    # Main configuration with includes
├── threat-intel.toml      # Threat intelligence settings
├── session.toml          # Session management configuration
└── methods/              # Authentication method configs
    ├── oauth2.toml       # OAuth2 provider settings
    ├── jwt.toml          # JWT method configuration
    ├── mfa.toml          # Multi-factor authentication
    └── api_key.toml      # API key authentication

Parent Application Integration

Auth-framework configuration seamlessly integrates into larger application configs:

# your-app.toml
[app]
name = "MyApplication"
version = "1.0.0"

# Include auth-framework configuration
[auth]
include = ["auth-framework.toml"]

# Override specific auth settings
[auth.jwt]
secret_key = "production-secret"
issuer = "myapp.com"

For complete configuration documentation, see:

config/INTEGRATION_GUIDE.md - Parent app integration patterns
config/EXAMPLES.md - Practical configuration examples
config/ directory - Example modular configuration files

Security Considerations

Secret Management: Never hardcode secrets. Use environment variables or secure vaults.
Token Storage: Use secure storage backends in production (PostgreSQL recommended, Redis for sessions).
HTTPS: Always use HTTPS in production to protect tokens in transit.
Rate Limiting: Enable rate limiting to prevent brute force attacks.
Token Expiration: Set appropriate token lifetimes based on your security requirements.
Audit Logging: Enable comprehensive audit logging for security monitoring.

RSA Key Format Support

When using RSA keys for JWT signing and verification, the framework supports both standard PEM formats:

Supported Formats

PKCS#1 Format (Traditional RSA format):

-----BEGIN RSA PRIVATE KEY-----
-----END RSA PRIVATE KEY-----

PKCS#8 Format (Modern standard format, recommended):

-----BEGIN PRIVATE KEY-----
-----END PRIVATE KEY-----

Usage

Both formats are automatically detected and work seamlessly with the TokenManager:

use auth_framework::tokens::TokenManager;

// Load your RSA keys (either PKCS#1 or PKCS#8 format)
let private_key = std::fs::read("private.pem")?;
let public_key = std::fs::read("public.pem")?;

// Create token manager - format is auto-detected
let token_manager = TokenManager::new_rsa(
    &private_key,
    &public_key,
    "your-issuer",
    "your-audience"
)?;

Key Generation

Generate RSA keys in your preferred format:

# Generate PKCS#1 format (traditional)
openssl genrsa -out private.pem 2048
openssl rsa -in private.pem -pubout -out public.pem

# Generate PKCS#8 format (recommended)
openssl genpkey -algorithm RSA -out private_pkcs8.pem -pkcs8
openssl pkey -in private_pkcs8.pem -pubout -out public_spki.pem

Note: No format conversion is required - the framework handles both formats automatically.

Testing Your Authentication Code

The framework provides comprehensive testing utilities to make testing your authentication logic easy:

[dev-dependencies]
auth-framework = { version = "0.5.0-rc18", features = ["testing"] }

use auth_framework::{
    testing::{MockAuthMethod, MockStorage, helpers},
    AuthFramework, AuthConfig, Credential,
};

#[tokio::test]
async fn test_user_authentication() {
    // Create a test auth framework
    let mut auth = helpers::create_test_auth_framework();

    // Set up a mock authentication method
    let mock_method = MockAuthMethod::new_success()
        .with_user("testuser".to_string(), helpers::create_test_user_profile("testuser"));

    auth.register_method("mock", Box::new(mock_method));
    auth.initialize().await.unwrap();

    // Test authentication
    let credential = Credential::password("testuser", "password");
    let result = auth.authenticate("mock", credential).await.unwrap();

    match result {
        auth_framework::AuthResult::Success(token) => {
            assert_eq!(token.user_id, "testuser");
            assert!(token.scopes.contains(&"read".to_string()));
        }
        _ => panic!("Expected successful authentication"),
    }
}

#[tokio::test]
async fn test_authentication_failure() {
    let mut auth = helpers::create_test_auth_framework();

    // Mock method that always fails
    let mock_method = MockAuthMethod::new_failure();
    auth.register_method("mock", Box::new(mock_method));
    auth.initialize().await.unwrap();

    let credential = Credential::password("testuser", "wrong_password");
    let result = auth.authenticate("mock", credential).await.unwrap();

    match result {
        auth_framework::AuthResult::Failure(_) => {
            // Expected
        }
        _ => panic!("Expected authentication failure"),
    }
}

#[tokio::test]
async fn test_token_storage() {
    let storage = MockStorage::new();
    let token = helpers::create_test_token("testuser");

    // Store and retrieve token
    storage.store_token(&token).await.unwrap();
    let retrieved = storage.get_token(&token.id).await.unwrap();

    assert!(retrieved.is_some());
    assert_eq!(retrieved.unwrap().user_id, "testuser");
}

Error Handling

The framework provides specific error types for better error handling:

use auth_framework::{AuthError, DeviceFlowError, OAuthProviderError};

async fn handle_auth_errors() {
    // Device flow specific errors
    match some_device_flow_operation().await {
        Err(AuthError::DeviceFlow(DeviceFlowError::AuthorizationPending)) => {
            println!("User hasn't completed authorization yet");
        }
        Err(AuthError::DeviceFlow(DeviceFlowError::SlowDown)) => {
            println!("Polling too frequently, slowing down");
        }
        Err(AuthError::DeviceFlow(DeviceFlowError::ExpiredToken)) => {
            println!("Device code expired, need to restart flow");
        }
        Err(AuthError::DeviceFlow(DeviceFlowError::AccessDenied)) => {
            println!("User denied authorization");
        }
        _ => {}
    }

    // OAuth provider specific errors
    match some_oauth_operation().await {
        Err(AuthError::OAuthProvider(OAuthProviderError::InvalidAuthorizationCode)) => {
            println!("Authorization code is invalid or expired");
        }
        Err(AuthError::OAuthProvider(OAuthProviderError::InsufficientScope { required, granted })) => {
            println!("Insufficient permissions: need '{}', got '{}'", required, granted);
        }
        Err(AuthError::OAuthProvider(OAuthProviderError::RateLimited { message })) => {
            println!("Rate limited by provider: {}", message);
        }
        _ => {}
    }

    // General auth errors
    match some_auth_operation().await {
        Err(AuthError::InvalidCredential { credential_type, message }) => {
            println!("Invalid {}: {}", credential_type, message);
        }
        Err(AuthError::Timeout { timeout_seconds }) => {
            println!("Operation timed out after {} seconds", timeout_seconds);
        }
        Err(AuthError::ProviderNotConfigured { provider }) => {
            println!("Provider '{}' is not configured", provider);
        }
        _ => {}
    }
}

Provider Configuration

OAuth providers are available for server-side implementations. See the server examples for complete provider usage:

use auth_framework::providers::{OAuthProvider, OAuthProviderConfig, UserProfile};
use std::collections::HashMap;

// Available providers for OAuth server implementations
let github_provider = OAuthProvider::GitHub;
let google_provider = OAuthProvider::Google;
let microsoft_provider = OAuthProvider::Microsoft;

// Custom provider configuration
let custom_provider = OAuthProvider::Custom {
    name: "My Provider".to_string(),
    config: OAuthProviderConfig {
        authorization_url: "https://auth.example.com/authorize".to_string(),
        token_url: "https://auth.example.com/token".to_string(),
        device_authorization_url: Some("https://auth.example.com/device".to_string()),
        userinfo_url: Some("https://auth.example.com/userinfo".to_string()),
        revocation_url: Some("https://auth.example.com/revoke".to_string()),
        default_scopes: vec!["read".to_string(), "profile".to_string()],
        supports_pkce: true,
        supports_refresh: true,
        supports_device_flow: true,
        additional_params: HashMap::new(),
    },
};

// For complete OAuth server implementation examples, see:
// - examples/oauth2_authorization_server.rs
// - examples/complete_oauth2_server_axum.rs

User Profile Standardization

The framework provides a standardized UserProfile type that works across all providers:

use auth_framework::providers::UserProfile;

// Creating user profiles
let profile = UserProfile::new("user123", "github")
    .with_name("John Doe")
    .with_email("john@example.com")
    .with_email_verified(true)
    .with_picture("https://github.com/avatar.jpg")
    .with_locale("en-US")
    .with_additional_data("github_login".to_string(), serde_json::Value::String("johndoe".to_string()));

// Converting to your application's user type
#[derive(serde::Deserialize)]
struct AppUser {
    id: String,
    name: String,
    email: String,
    avatar_url: Option<String>,
}

impl From<UserProfile> for AppUser {
    fn from(profile: UserProfile) -> Self {
        Self {
            id: profile.id,
            name: profile.name.unwrap_or_default(),
            email: profile.email.unwrap_or_default(),
            avatar_url: profile.picture,
        }
    }
}

// Usage
let app_user: AppUser = user_profile.into();

Credential Types Guide

Understanding the relationship between credentials and authentication methods:

use auth_framework::Credential;

// Password credentials -> PasswordMethod
let password_cred = Credential::password("username", "password");

// API key -> ApiKeyMethod
let api_key_cred = Credential::api_key("your_api_key_here");

// JWT token -> JwtMethod
let jwt_cred = Credential::jwt("jwt.token.string");

// OAuth flows are handled by the OAuth server implementation
// See server examples for complete OAuth credential handling
let device_cred = Credential::Custom {
    method: "device_code".to_string(),
    data: {
        let mut data = HashMap::new();
        data.insert("device_code".to_string(), "device_code_string".to_string());
        data.insert("client_id".to_string(), "your_client_id".to_string());
        data
    }
};

// Multi-factor authentication
let mfa_cred = Credential::Mfa {
    primary_credential: Box::new(password_cred),
    mfa_code: "123456".to_string(),
    challenge_id: "mfa_challenge_id".to_string(),
};

// Custom credentials for custom auth methods
let custom_cred = Credential::Custom {
    method: "custom_auth".to_string(),
    data: {
        let mut data = HashMap::new();
        data.insert("token".to_string(), "custom_token".to_string());
        data.insert("signature".to_string(), "signature_string".to_string());
        data
    }
};

CLI Integration

Helper utilities for integrating with CLI frameworks:
