Combined with other API gateway capabilities, NGINX Plus enables you to deliver APIbased services with speed, reliability, scalability, and security. The NGINX Plus R10 release comes with native support for the JWT authentication standard. . Finally, we provide the JWT subject as a new HTTP header when the request is proxied to the API endpoint. URI to be redirected by the IdP after successful logout from the IdP. Commands and encoded values appear on multiple lines only for readability; each one is actually typed as or appears on a single line. Parameter value can contain variables. Native JWT support is available only in NGINXPlus, not NGINX Open Source. Follow the steps in this guide to configure authentication for Instance Manager. ewogICAgInN1YiI6ICJsYzEiLAogICAgImVtYWlsIjo When we decode our sample JWT we see: The JWT standard defines several signature algorithms. JWTs have three parts: a header, a payload, and a signature. This documentation applies to NGINX Management Suite Instance Manager 2.0.0 and later. Now we have everything we need to create the JWT, we follow these steps to correctly encode and sign it. It is common to apply different access controls and policies to different API clients. To be valid, the $jwt_status variable must not be empty, and not equal to 0 (zero). Sets the variable to a JWT claim parameter This deactivation will work even if you later click Accept or submit a form. After validating the JWT, NGINXPlus has access to all of the fields present in the header and the payload as variables. In this blog post we describe how to use NGINXPlus as an API gateway, providing a frontend to an API endpoint and using JWTs to authenticate client applications. The module can be used for OpenID Connect authentication. The commercial version of NGINX, NGINX Plus, has built-in JWT handling features. and Support Plugin: JWT Auth - WordPress JSON Web Token Authentication Configure JWT with Nginx. The NGINX Plus configuration for validating JWTs is very simple. List of the OAuth 2.0 scope values that this server supports. and You can use your identity provider (IdP) or your own service to create JWTs. The iss field describes the issuer of the JWT, which is useful if your API gateway also accepts JWTs from thirdparty issuers or a centralized identity management system. Authentication is required for the IdP to accept token introspection requests from this NGINX instance. The value HS256 in our example refers to HMACSHA256, which were using for all sample JWTs in this blog post. or from a subrequest, JWT claims. In transmission, they look like the following. # Successfully authenticated users are proxied to the backend, /var/log/nginx/nginx-manager-jwt-access.log, NGINX Microservices Reference Architecture, Publish an API Gateway and Developer Portal, Enable Creating Credentials on the Developer Portal, Enable Single Sign-On for Developer Portal, Restricting Access with HTTP Basic Authentication, Configure OIDC with Azure Active Directory, Set up Azure Active Directory as an OIDC Identity Provider. This directive appeared in version 1.21.2. You need to create the JWT or use an identity provider (idP) to generate the JWT. You can use advanced NGINX Plus features such as JWT and gRPC by following the guides on the NGINX blog. The first thing we do is specify the addresses of the servers that host the API endpoint in the upstream block. If none of the directives are specified, JWS signature verification will be skipped. The auth_jwt directive defines the authentication realm that will be returned (along with a 401 status code) if authentication is unsuccessful. You need to create the JWT or use an identity provider (idP) to generate the JWT. NGINXPlus provides support for JWT authentication and sophisticated configuration solutions based on the information contained within the JWT itself. that contains JSON Web Token. URL of the IdPs OAuth 2.0 Authorization endpoint. nbf # ssl_client_certificate /etc/ssl/nginx-manager/ca.pem; EECDH+CHACHA20:EECDH+AES128:RSA+AES128:EECDH+AES256:RSA+AES256:EECDH+3DES:RSA+3DES:!MD5, # Could change to /api for multiple methods of auth, # Change to realm you use or "" for no realm. Deployers of APIs and microservices are also turning to the JWT standard for its simplicity and flexibility. Together with F5, our combined solution bridges the gap between NetOps and DevOps, with multi-cloud application services that span from code to customer. Generally, the API endpoint does not validate API keys itself; instead an API gateway handles the authentication process and routes each request to the appropriate endpoint. The NGINXPlus configuration for validating JWTs is very simple. Notice too that the nginx-jwt script has tacked on an extra response header called X-Auth-UserId that contains the value passed in the JWT payload's subject. Authentication Server will validate those credentials and store them somewhere on the browser session and cookies and send the ID to the end-user. The following information is needed to configure the service: Table: OIDC Metadata via Well-Known Endpoints, Table: OIDC Custom Configuration for Well-Known Endpoints. In addition to authentication, JWTs can also be used to pass information, called claims, about the user to the application. Learn how this can change the way your app handles authentication. We explain how to configure the gateway for JWT-based authentication, issue JWTs to API clients, rate limit, log claims from the JWT, and revoke JWTs. Then, run okta apps create. EdDSA (Ed25519 and Ed448 signatures) (1.15.7), A128CBC-HS256, A192CBC-HS384, A256CBC-HS512, dir- direct use of a shared symmetric key as the content encryption key, RSA-OAEP, RSA-OAEP-256, RSA-OAEP-384, RSA-OAEP-512 (1.21.0). Without NGINX Plus to protect our API routes, we'd have to add a couple more dependencies, add some middleware to check and verify that the incoming request had a valid . If you already have an account, run okta login . As a sample API client, well use a quotation system application and create a JWT for the API client. inherited from the previous configuration level. Hi there, . The topic 'Configure JWT with Nginx' is closed to new replies. JWTs have three parts: a header, a payload, and a signature. JSON Web Key Set The location block specifies that any requests to URLs beginning with /products/ must be authenticated. With JWT, these attributes are embedded, negating the need for a separate lookup. NGINX Plus also supports the RS256 and EC256 signature algorithms that are defined in the standard. The values of three resulting variables are evaluated in the auth_jwt_require directive, and if the value of each variable is 1, the JWT will be accepted: In some cases the auth_jwt_require directive can be specified multiple times, for example, for the purpose of authentication and then for authorization. The following content encryption algorithms (the enc field of JWE header) are supported: The following key management algorithms (the alg field of JWE header) are supported: Nested JWT - support for JWS enclosed into JWE. See the original article here. sy007 (@sy007) 1 year, 8 months ago. This example sums up the previous steps into one configuration: Copyright F5, Inc.

For arrays, the variable keeps a list of array elements separated by commas. The module supports The only caveat is to uncomment the redirect_uri and fill that in but instead comment out or remove the redirect_uri_path which is a deprecated field. allows redefining the error code to 403. Skip to content Your Cookie Settings The first thing we do is specify the addresses of the servers that host the API endpoint, in the upstream block. The JWT specification has been an important underpinning of OpenID Connect, providing a single signon token for the OAuth 2.0 ecosystem. This can be done with the auth_jwt_key_file and/or auth_jwt_key_request directives. ngx_http_auth_basic_module, With JWT, these attributes are embedded, negating the need for a separate lookup. Explore the areas where NGINX can help your organization overcome specific technical challenges. The ability to cryptographically sign JWTs makes them ideal for use as authentication credentials. The ability to cryptographically sign JWTs makes them ideal for use as authentication credentials. Finally, we provide the JWT subject as a new HTTP header when the request is proxied to the API endpoint. Now we are ready to issue JWTs to our API clients. IdPs client secret which is used by the client to exchange an authorization code for a token. The JWT specification has been an important underpinning of OpenID Connect, providing a single signon token for the OAuth 2.0 ecosystem. Share! With JWT authentication, a client provides a JSON Web Token, and the token will be validated against a local key file or a remote service. Sign the header and payload with our symmetric key and Base64URLencode the signature. Test by making an authenticated request to the API gateway (in this example, the gateway is running on localhost). gImxpYW0uY3JpbGx5QG5naW54LmNvbSIsCn0=, VGYHWPterIaLjRi0LywgN3jnDUQbSsFptUw99g2slfc, ewogICAgInN1YiI6ICJsYzEiLAogICAgImVtYWlsIjogImxpYW0uY3JpbGx5QG5naW54LmNvbSIsCn0=.

Decrypt operation on the application side may be time and resource consuming. Get technical and business-oriented blogs that help you address key technology challenges. sets the URI where the subrequest will be sent to. Now that we have everything we need to create the JWT, we follow these steps to correctly encode and sign it. For more examples, refer to the NGINX documentation Setting up JWT Authentication. Parameter value can contain variables. Using simple map and if blocks, we can deny access to an API client by marking its JWT as revoked until such time as the JWTs exp claim (expiration date) is reached, at which point the map entry for that JWT can be safely removed. A common way to authenticate an API client (the remote software client requesting API resources) is through a shared secret, generally referred to as an API key. Uncheck it to withdraw consent. Accept cookies for analytics, social media, and advertising, or learn more and adjust your preferences. Nested JWT (nested) (1.21.0). This is particularly useful when multiple API clients are embedded in a single portal and cannot be differentiated by IP address. Therefore the API endpoint does not need to implement any JWT processing logic. Install the NGINX JavaScript module (njs). Note each users username for step 2. You may find additional configuration tips and documentation for this module in the GitHub repository for nginx-module-auth-ldap. powered by Disqus. Weve added line breaks for readability (the actual JWT is a single string). Authenticating API Clients With JWT and NGINX Plus, Docker Files and Volumes: Permission Denied, iOS Meets IoT: Five Steps to Building Connected Device Apps for Apple, What Does Synchronization With Asyncio Look Like, Top 15 Angular Frameworks and Libraries for Web Development. the value of the variable cannot be evaluated; Test by making an authenticated request to the API gateway (in this example, the gateway is running on localhost). , JSON Web Token (JWT) NGINX Plus Release 10 introduced support for offloading authentication from web and API services with JSON Web Tokens (JWTs, pronounced "jots"). Lets assume that NGINX Plus serves as a gateway (proxy_pass http://api_server) to a number of API servers (the upstream {} block), and requests passed to the API servers should be authenticated: First, it is necessary to create a JWT that will be issued to a client. Turning on caching is recommended for high-load API gateways even if JWT key caching is used as it will help to avoid overwhelming a key server with key requests when a JWT key cache expires.
