Struct JwtAuthenticator 

pub struct JwtAuthenticator { /* private fields */ }

JWT-based authenticator.

Extracts and validates JWT tokens from the Authorization header.

Spring Security Equivalent

Similar to JwtAuthenticationProvider with BearerTokenAuthenticationFilter.

Example

use actix_security_core::http::security::jwt::{JwtAuthenticator, JwtConfig};

let config = JwtConfig::new("your-256-bit-secret-key-here!")
    .issuer("my-app")
    .expiration_hours(24);

let authenticator = JwtAuthenticator::new(config);

// Use with SecurityTransform
SecurityTransform::new()
    .config_authenticator(move || authenticator.clone())
    .config_authorizer(|| /* ... */)

Implementations

impl JwtAuthenticator

pub fn new(config: JwtConfig) -> JwtAuthenticator

Create a new JWT authenticator.

pub fn config(&self) -> &JwtConfig

Get the configuration.

pub fn generate_token(&self, user: &User) -> Result<String, JwtError>

Generate a JWT token for a user.

Example

let token = authenticator.generate_token(&user)?;
// Returns: "eyJhbGciOiJIUzI1NiIsInR5cCI6IkpXVCJ9..."

pub fn generate_token_with_claims( &self, claims: &Claims, ) -> Result<String, JwtError>

Generate a token with custom claims.

pub fn validate_token(&self, token: &str) -> Result<TokenData<Claims>, JwtError>

Validate a token and return the claims.

impl JwtAuthenticator

pub fn validate_token_rsa( &self, token: &str, ) -> Result<TokenData<Claims>, JwtError>

Validate token with RSA public key.

Note: This method works when JwtConfig was created with with_rsa_public_key.
