# OpenIddict

### The OpenID Connect stack you'll be addicted to.

[![Build status](https://github.com/openiddict/openiddict-core/workflows/build/badge.svg?branch=dev&event=push)](https://github.com/openiddict/openiddict-core/actions?query=workflow%3Abuild+branch%3Adev+event%3Apush)

## What's OpenIddict?

OpenIddict aims at providing a **versatile solution** to implement **OpenID Connect client, server and token validation support in any ASP.NET Core 2.1 (and higher) application**.
**ASP.NET 4.6.1 (and higher) applications are also fully supported thanks to a native Microsoft.Owin 4.2 integration**.

OpenIddict fully supports the **[code/implicit/hybrid flows](http://openid.net/specs/openid-connect-core-1_0.html)**,
the **[client credentials/resource owner password grants](https://tools.ietf.org/html/rfc6749)** and the [device authorization flow](https://tools.ietf.org/html/rfc8628).

OpenIddict natively supports **[Entity Framework Core](https://www.nuget.org/packages/OpenIddict.EntityFrameworkCore)**,
**[Entity Framework 6](https://www.nuget.org/packages/OpenIddict.EntityFramework)** and **[MongoDB](https://www.nuget.org/packages/OpenIddict.MongoDb)**
out-of-the-box and custom stores can be implemented to support other providers.

--------------

## Getting started

**Developers looking for a simple and turnkey solution are strongly encouraged to use [OrchardCore and its OpenID module](https://docs.orchardcore.net/en/dev/docs/reference/modules/OpenId/)**,
which is based on OpenIddict, comes with sensible defaults and offers a built-in management GUI to easily register OpenID client applications.

**To implement a custom OpenID Connect server using OpenIddict, read [Getting started](https://documentation.openiddict.com/guides/getting-started.html)**.

**Samples demonstrating how to use OpenIddict with the different OAuth 2.0/OpenID Connect flows**
can be found in the [dedicated repository](https://github.com/openiddict/openiddict-samples).

:exclamation: **Note: ASP.NET Core 2.1 on .NET Core 2.1 and ASP.NET Core 5.0 on .NET 5.0 are no longer supported. While OpenIddict 4.x can still be
used on .NET Core 2.1 thanks to its .NET Standard 2.0 compatibility, users are strongly encouraged to migrate to ASP.NET Core/.NET 6.0**.
ASP.NET Core 2.1 on .NET Framework 4.6.1 (and higher) is still fully supported.

:information_source: **Note: the following features are not available when targeting .NET Framework 4.6.1**:
 - X.509 development encryption/signing certificates: calling `AddDevelopmentEncryptionCertificate()` or `AddDevelopmentSigningCertificate()`
will result in a `PlatformNotSupportedException` being thrown at runtime if no valid development certificate can be found and a new one must be generated.
 - X.509 ECDSA signing certificates/keys: calling `AddSigningCertificate()` or `AddSigningKey()`
with an ECDSA certificate/key will always result in a `PlatformNotSupportedException` being thrown at runtime.

--------------

## Certification

Unlike many other identity providers, **OpenIddict is not a turnkey solution but a framework that requires writing custom code**
to be operational (typically, at least an authorization controller), making it a poor candidate for the certification program.

While a reference implementation could be submitted as-is, **this wouldn't guarantee that implementations deployed by OpenIddict users would be standard-compliant.**

Instead, **developers are encouraged to execute the conformance tests against their own deployment** once they've implemented their own logic.

> The samples repository contains [a dedicated sample](https://github.com/openiddict/openiddict-samples/tree/dev/samples/Contruum/Contruum.Server) specially designed to be used
> with the OpenID Connect Provider Certification tool and demonstrate that OpenIddict can be easily used in a certified implementation. To allow executing the certification tests
> as fast as possible, that sample doesn't include any membership or consent feature (two hardcoded identities are proposed for tests that require switching between identities).
