Ory Keto is the first and most popular open source implementation of "Zanzibar:

Google's Consistent, Global Authorization System"!



## Get Started



You can use

[Docker to run Ory Keto locally](https://www.ory.sh/docs/keto/install) or use

the Ory CLI to try out Ory Keto:



```sh

# This example works best in Bash

bash <(curl https://raw.githubusercontent.com/ory/meta/master/install.sh) -b . ory

sudo mv ./ory /usr/local/bin/



# Or with Homebrew installed

brew install ory/tap/cli

```



create a new project (you may also use

[Docker](https://www.ory.sh/docs/keto/install))



```sh

ory create project --name "Ory Keto Example"

export project_id="{set to the id from output}"

```



and follow the quick & easy steps below.



## Create a namespace with the Ory Permission Language



```sh

# Write a simple configuration with one namespace

echo "class Document implements Namespace {}" > config.ts



# Apply that configuration

ory patch opl --project $project_id -f file://./config.ts



# Create a relationship that grants tom access to a document

echo "Document:secret#read@tom" \

  | ory parse relation-tuples --project=$project_id --format=json - \

  | ory create relation-tuples --project=$project_id -



# List all relationships

ory list relation-tuples --project=$project_id

# Output:

#   NAMESPACE	OBJECT	RELATION NAME	SUBJECT

#   Document	secret	read		tom

#

#   NEXT PAGE TOKEN

#   IS LAST PAGE	true

```



Now, check out your project on the [Ory Network](https://console.ory.sh/) or

continue with a [more in-depth guide](https://www.ory.sh/docs/keto/quickstart).



### Ory Keto on the Ory Network



The [Ory Network](https://www.ory.sh/cloud) is the fastest, most secure and

worry-free way to use Ory's Services. **Ory Permissions** is powered by the Ory

Keto open source permission server, and it's fully API-compatible.



The Ory Network provides the infrastructure for modern end-to-end security:



- Identity & credential management scaling to billions of users and devices

- Registration, Login and Account management flows for passkey, biometric,

  social, SSO and multi-factor authentication

- Pre-built login, registration and account management pages and components

- OAuth2 and OpenID provider for single sign on, API access and

  machine-to-machine authorization

- **Low-latency permission checks based on Google's Zanzibar model and with

  built-in support for the Ory Permission Language**



It's fully managed, highly available, developer & compliance-friendly!



- GDPR-friendly secure storage with data locality

## Ory Permissions, Keto and the Google's Zanzibar model



> Determining whether online users are authorized to access digital objects is

> central to preserving privacy. This paper presents the design, implementation,

> and deployment of Zanzibar, a global system for storing and evaluating access

> control lists. Zanzibar provides a uniform data model and configuration

> language for expressing a wide range of access control policies from hundreds

> of client services at Google, including Calendar, Cloud, Drive, Maps, Photos,

> and YouTube. Its authorization decisions respect causal ordering of user

> actions and thus provide external consistency amid changes to access control

> lists and object contents. Zanzibar scales to trillions of access control

> lists and millions of authorization requests per second to support services

> used by billions of people. It has maintained 95th-percentile latency of less

> than 10 milliseconds and availability of greater than 99.999% over 3 years of

> production use.

If you need to know if a user (or robot, car, service) is allowed to do

something - Ory Permissions and Ory Keto are the right fit for you.



Currently, Ory Permissions [on the Ory Network] and the open-source Ory Keto

permission server implement the API contracts for managing and checking

relations ("permissions") with HTTP and gRPC APIs, as well as global rules

defined through the Ory Permission Language ("userset rewrites"). Future

versions will include features such as Zookies, reverse permission lookups, and

more.

Many thanks to all individual contributors






\* Uses one of Ory's major projects in production.



## Installation



Head over to the documentation to learn about ways of

[installing Ory Keto](https://www.ory.sh/docs/keto/install).



## 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 is designed to run best on a Container Orchestration system

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 which easily connects to any existing identity system by

writing a tiny "bridge" application. It gives absolute control over the user

interface and user experience flows.



### 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.



## Security



### Disclosing Vulnerabilities



If you think you found a security vulnerability, please refrain from posting it

publicly on the forums, the chat, or GitHub. You can find all info for

responsible disclosure in our

[security.txt](https://www.ory.sh/.well-known/security.txt).



## Telemetry



Our services collect summarized, anonymized data which can optionally be turned

off. Click [here](https://www.ory.sh/docs/ecosystem/sqa) to learn more.



### Guide



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



### HTTP API Documentation



The HTTP API is documented [here](https://www.ory.sh/docs/keto/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 `keto -h` or `keto help`.



### Develop



We encourage all contributions and recommend you read our

[contribution guidelines](./CONTRIBUTING.md).



#### Dependencies



You need Go 1.19+ and (for the test suites):



- Docker and Docker Compose

- GNU Make 4.3

- NodeJS / npm >= v7



It is possible to develop Ory Keto on Windows, but please be aware that all

guides assume a Unix shell like bash or zsh.



#### Install From Source




make install




#### Formatting Code



You can format all code using make format. Our

CI checks if your code is properly formatted.



#### Running Tests



There are two types of tests you can run:



- Short tests (do not require a SQL database like PostgreSQL)

- Regular tests (do require PostgreSQL, MySQL, CockroachDB)



##### Short Tests



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



```shell script

go test -short -tags sqlite ./...

```



or test just a specific module:



```shell script

go test -tags sqlite -short ./internal/check/...

```



##### 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 script instead. Using dockertest can bloat the number of

Docker Images on your system and starting them on each run is quite slow.

Instead we recommend doing:



```shell

source ./scripts/test-resetdb.sh

go test -tags sqlite ./...

```



##### End-to-End Tests



The e2e tests are part of the normal `go test`. To only run the e2e test, use:



```shell

source ./scripts/test-resetdb.sh

go test -tags sqlite ./internal/e2e/...

```



or add the `-short` tag to only test against sqlite in-memory.



#### Build Docker



You can build a development Docker Image using:




make docker
