🚀 Announcing Beta release : A new Auth0 ASP.NET SDK to secure your API

[kailash-b]

We’re excited to announce the beta of our new resource server SDK: Auth0.AspNetCore.Authentication.Api — a modern, fluent, Auth0-optimised way to secure ASP.NET Core APIs.

Auth0.AspNetCore.Authentication.Api provides a cleaner, intuitive way to integrate token validation and authorisation into your services. It leverages the power of Microsoft.AspNetCore.Authentication.JwtBearer while abstracting away the complex configuration and policy setup needed to work with Auth0.

✨ Key Features

• ✅ Complete JWT Bearer Functionality: Full compatibility with all features from Microsoft.AspNetCore.Authentication.JwtBearer.
  -🛡️ Built-in DPoP Support: Enhanced security with Demonstrating-Proof-Of-Possession security as defined by RFC 9449.
  -⚡ Auth0 Optimized: Pre-configured settings to align with standard Auth0 authentication patterns.
• 🎛️ Flexible Configuration: Utilises the options pattern, providing full access to the underlying JWT Bearer configuration.
• 🔒 Zero Lock-in: Benefit from DPoP enhancements while retaining the ability to use standard JWT Bearer features.

builder.Services.AddAuth0ApiAuthentication(options =>
{
    options.Domain = builder.Configuration["Auth0:Domain"];
    options.JwtBearerOptions = new JwtBearerOptions
    {
        Audience = builder.Configuration["Auth0:Audience"]
    };
});
