ORY Hydra is a hardened, **OpenID Certified OAuth 2.0 Server and OpenID Connect Provider** optimized for low-latency, high throughput,
and low resource consumption. ORY Hydra *is not* an identity provider (user sign up, user login, password reset flow),
but connects to your existing identity provider through a [login and consent app](https://www.ory.sh/docs/next/hydra/oauth2#authenticating-users-and-requesting-consent).
Implementing the login and consent app in a different language is easy, and exemplary consent apps
([Go](https://github.com/ory/hydra-consent-app-go), [Node](https://github.com/ory/hydra-consent-app-express)) and
[SDKs](https://www.ory.sh/docs/next/hydra/sdk/) are provided.

Besides mitigating various attack vectors, such as database compromisation and OAuth 2.0 weaknesses, ORY Hydra is also
able to securely manage JSON Web Keys.

## What is ORY Hydra?

ORY Hydra is a server implementation of the OAuth 2.0 authorization framework and the OpenID Connect Core 1.0. Existing OAuth2
implementations usually ship as libraries or SDKs such as [node-oauth2-server](https://github.com/oauthjs/node-oauth2-server)
or [fosite](https://github.com/ory/fosite/issues), or as fully featured identity solutions with user
management and user interfaces, such as [Dex](https://github.com/coreos/dex).

Implementing and using OAuth2 without understanding the whole specification is challenging and prone to errors, even when
SDKs are being used. The primary goal of ORY Hydra is to make OAuth 2.0 and OpenID Connect 1.0 better accessible.

ORY Hydra implements the flows described in OAuth2 and OpenID Connect 1.0 without forcing you to use a "Hydra User Management"
or some template engine or a predefined front-end. Instead it relies on HTTP redirection and cryptographic methods
to verify user consent allowing you to use ORY Hydra with any authentication endpoint, be it [authboss](https://github.com/go-authboss/authboss), [User Frosting](https://www.userfrosting.com/) or your proprietary Java authentication.

### Installation

Head over to the [ORY Developer Documentation](https://www.ory.sh/docs/next/hydra/configure-deploy#installing-ory-hydra) to learn how to install ORY Hydra on Linux, macOS, Windows, and Docker and how to build ORY Hydra from source.

## Ecosystem

<!--BEGIN ECOSYSTEM-->

We build Ory on several guiding principles when it comes to our architecture
design:

- Minimal dependencies
- Runs everywhere
- Scales without effort
- Minimize room for human and network errors

ORY's architecture designed to run best on a Container Orchestration Systems
such as Kubernetes, CloudFoundry, OpenShift, and similar projects. Binaries are
small (5-15MB) and available for all popular processor types (ARM, AMD64, i386)
and operating systems (FreeBSD, Linux, macOS, Windows) without system
dependencies (Java, Node, Ruby, libxml, ...).

### ORY Kratos: Identity and User Infrastructure and Management

[ORY Kratos](https://github.com/ory/kratos) is an API-first Identity and User
Management system that is built according to
[cloud architecture best practices](https://www.ory.sh/docs/next/ecosystem/software-architecture-philosophy).
It implements core use cases that almost every software application needs to
deal with: Self-service Login and Registration, Multi-Factor Authentication
(MFA/2FA), Account Recovery and Verification, Profile and Account Management.

### ORY Hydra: OAuth2 & OpenID Connect Server

[ORY Hydra](https://github.com/ory/hydra) is an OpenID Certified™ OAuth2 and
OpenID Connect Provider can connect to any existing identity database (LDAP, AD,
KeyCloak, PHP+MySQL, ...) and user interface.

### ORY Oathkeeper: Identity & Access Proxy

[ORY Oathkeeper](https://github.com/ory/oathkeeper) is a BeyondCorp/Zero Trust
Identity & Access Proxy (IAP) with configurable authentication, authorization,
and request mutation rules for your web services: Authenticate JWT, Access
Tokens, API Keys, mTLS; Check if the contained subject is allowed to perform the
request; Encode resulting content into custom headers (`X-User-ID`), JSON Web
Tokens and more!

### ORY Keto: Access Control Policies as a Server

[ORY Keto](https://github.com/ory/keto) is a policy decision point. It uses a
set of access control policies, similar to AWS IAM Policies, in order to
determine whether a subject (user, application, service, car, ...) is authorized
to perform a certain action on a resource.

<!--END ECOSYSTEM-->





















## Security

*Why should I use ORY Hydra? It's not that hard to implement two OAuth2 endpoints and there are numerous SDKs out there!*

OAuth2 and OAuth2 related specifications are over 400 written pages. Implementing OAuth2 is easy, getting it right is hard.
ORY Hydra is trusted by companies all around the world, has a vibrant community and faces millions of requests in production
each day. Of course, we also compiled a security guide with more details on cryptography and security concepts.
Read [the security guide now](https://www.ory.sh/docs/next/hydra/security-architecture).

### Disclosing vulnerabilities

If you think you found a security vulnerability, please refrain from posting it publicly on the forums, the chat, or GitHub
and send us an email to [hi@ory.am](mailto:hi@ory.sh) instead.

## Benchmarks

Our continuous integration runs a collection of benchmarks against ORY Hydra. You can find the results [here](https://www.ory.sh/docs/next/performance/hydra).

## Telemetry

Our services collect summarized, anonymized data that can optionally be turned off. Click
[here](https://www.ory.sh/docs/next/ecosystem/sqa) to learn more.

## Documentation

### Guide

The Guide is available [here](https://www.ory.sh/docs/next/hydra).

### HTTP API documentation

The HTTP API is documented [here](https://www.ory.sh/docs/next/hydra/sdk/api).

### Upgrading and Changelog

New releases might introduce breaking changes. To help you identify and incorporate those changes, we document these
changes in [UPGRADE.md](./UPGRADE.md) and [CHANGELOG.md](./CHANGELOG.md).

### Command line documentation

Run `hydra -h` or `hydra help`.

### Develop

We encourage all contributions and encourage you to read our [contribution guidelines](./CONTRIBUTING.md).

#### Dependencies

You need Go 1.13+ with `GO111MODULE=on` and (for the test suites):

- Docker and Docker Compose
- Makefile
- NodeJS / npm

It is possible to develop ORY Hydra on Windows, but please be aware that all guides assume a Unix shell like bash or zsh.

#### Workflows

##### Install Tools

When cloning ORY Hydra, run `make deps`. It will download several required dependencies. If you haven't run the command
in a while it's probably a good idea to run it again.

#### Formatting Code

You can format all code using `make format`. Our CI checks if your code is properly formatted.

#### Running Tests

There are three types of tests you can run:

- Short tests (do not require a SQL database like PostgreSQL)
- Regular tests (do require PostgreSQL, MySQL, CockroachDB)
- End to end tests (do require databases and will use a test browser)

##### Short Tests

Short tests run fairly quickly. You can either test all of the code at once:

```shell script
go test -short ./...
```

or test just a specific module:

```shell script
cd client; go test -short .
```

##### Regular Tests

Regular tests require a database set up. Our test suite is able to work with docker directly (using [ory/dockertest](https://github.com/ory/dockertest))
but we encourage to use the Makefile instead. Using dockertest can bloat the number of Docker Images on your system
and are quite slow. Instead we recommend doing:

```shell script
make test
```

Please be aware that `make test` recreates the databases every time you run `make test`. This can be annoying if
you are trying to fix something very specific and need the database tests all the time. In that case we
suggest that you initialize the databases with:

```shell script
make resetdb
export TEST_DATABASE_MYSQL='mysql://root:secret@(127.0.0.1:3444)/mysql?parseTime=true&multiStatements=true'
export TEST_DATABASE_POSTGRESQL='postgres://postgres:secret@127.0.0.1:3445/postgres?sslmode=disable'
export TEST_DATABASE_COCKROACHDB='cockroach://root@127.0.0.1:3446/defaultdb?sslmode=disable'
```

Then you can run `go test` as often as you'd like:

```shell script
go test -p 1 ./...

# or in a module:
cd client; go test .
```

#### E2E Tests

The E2E tests use [Cypress](https://www.cypress.io) to run full browser tests. You can execute these tests with:

```
make e2e
```

The runner will not show the Browser window, as it runs in the CI Mode (background). That makes debugging these
type of tests very difficult, but thankfully you can run the e2e test in the browser which helps with debugging! Just run:

```shell script
./test/e2e/circle-ci.bash memory --watch

# Or for the JSON Web Token Access Token strategy:
# ./test/e2e/circle-ci.bash memory-jwt --watch
```

or if you would like to test one of the databases:

```shell script
make resetdb
export TEST_DATABASE_MYSQL='mysql://root:secret@(127.0.0.1:3444)/mysql?parseTime=true&multiStatements=true'
export TEST_DATABASE_POSTGRESQL='postgres://postgres:secret@127.0.0.1:3445/postgres?sslmode=disable'
export TEST_DATABASE_COCKROACHDB='cockroach://root@127.0.0.1:3446/defaultdb?sslmode=disable'

# You can test against each individual database:
./test/e2e/circle-ci.bash postgres --watch
./test/e2e/circle-ci.bash memory --watch
./test/e2e/circle-ci.bash mysql --watch
# ...
```

Once you run the script, a Cypress window will appear. Hit the button "Run all Specs"!

The code for these tests is located in [./cypress/integration](./cypress/integration) and
[./cypress/support](./cypress/support) and
[./cypress/helpers](./cypress/helpers). The website you're seeing is located in
[./test/e2e/oauth2-client](./test/e2e/oauth2-client).

#### Making SQL Changes

We embed the SQL files into the binary. If you make changes to any `.sql` file, you need to run:

```shell script
make sqlbin
```

#### Build Docker

You can build a development Docker Image using:

```shell script
make docker
```

#### Run the Docker Compose quickstarts

If you wish to check your code changes against any of the docker-compose quickstart files, run:

```shell script
make docker
docker compose -f quickstart.yml up # ....
```
